The Details

  • Grows With Your Child: One clever, adaptable cup replaces three separate drinkers, making it a smart investment.
  • Smart, Practical Design: Features a removable, dual-handle silicone sleeve with a textured grip, perfectly sized for little hands to hold with confidence.
  • Leak-Proof Sippy Lid: The upgraded sippy lid features a tight seal and a non-spill spout, allowing little learners to practice tilting and drinking independently without the messy aftermath.
  • Leak-Proof Straw System: We've solved the "straw splatter." Our new Straw Lid pairs with a leak-proof valve straw that prevents spills even when the cup is tipped upside down or dropped.
  • Built for Real Life: The shatter-proof stainless steel body easily survives pram tosses, high-chair drops, and daily tumbles.
  • Resists Odours & Stains: Unlike plastic, the electropolished stainless steel interior doesn't retain the tastes or smells of previous drinks (such as milk or juice).
  • Handy Volume Markers: Internal measurement lines (up to 220ml) help you easily track your child's daily hydration.
  • Effortless to Clean: The wide-mouth design allows for easy access, the sleeve is removable, and the straw detaches for a thorough clean. All parts are conveniently dishwasher-safe.

Transitioning from a bottle is a major milestone, and our customers love how this 3-in-1 system grows with their child's confidence. From the soft silicone spout to the independent straw, discover our tips for a tear-free transition in our Ultimate Sippy Cup & Transition Guide →

The Bigger Picture

  • A cup that grows with your family. From a toddler trainer to a kitchen measuring cup, and even assisted drinking for adults. See how Greenvyne products are designed for every stage of life.
  • Plastic-Free Packaging: Delivered to your door in fully recyclable and compostable materials.

  • A Conscious Alternative: Crafted from long-lasting stainless steel and silicone, offering a practical alternative to plastic for mindful families.

Dimensions & Care

How to attach the new leak-proof lids:

  1. Hold the cup and secure one side of the lid onto the steel rim.
  2. Using the pull tab, gently stretch and pull the lid over the rim with your thumb & index finger until fully seated.

How to fit the straw:

  1. Push the straw down through the straw lid hole until the straw stopper sits flush with the lid
  2. The silicone straw stopper is not designed to withstand forceful pulling or pushing. This is common at the 6–12 month stage and typically resolves as little ones grow.

Silicone sleeve:

  • The sleeve is removable for deep cleaning.

To remove, gently ease it off from the base. Do not pull from the handle area, as this can cause tearing over time.

Size:

  • Capacity – 250 ml (Internal volume marked up to 220ml)
  • Height – 10 cm
  • Rim – 7 cm
  • Weight – 131 g (with sleeve)

Care:

  • Top-rack dishwasher safe (all parts)
  • Hand-wash silicone lids often to keep the valves debris-free
  • Never microwave stainless steel, warm drinks in a hot-water bath
  • Bicarb + vinegar soak removes stubborn odours or stains

My baby loves it!

Baby loves it! I contacted the team as I was concerned about the design. They responded straight away and let me know that I was not fitting the lid properly. It’s a great sippy cup. I love that it’s stainless steel.

Thank you! I bought two as I lost the first! Baby also loves throwing it and I can tell you it’s very sturdy haha

Stainless cup

I brought this because my 1 year olds previous waterbottle was super hard to keep clean. I love that I can use this so many ways! I even take the top off and use it for soups and stocks. No yucky smell or residue left behind because the cup is stainless. I’m very impressed. Thank you so much for such a great product that is low tox and user friendly.

All rounder first cup

With extensive research finding my babys first all rounder sippy cup that can change between a sippy cup, normal open and spout. This was a no brainer using quality materials to ensure that the baby is able to use it for some years. Despite it being small I have found this to be more of a benefit rather than a detriment because the baby is able to grab onto to the cup alot easier and isn't heavy for them.

Thank you for your lovely review We’re so glad the 3-in-1 cup has been the perfect first cup and easy for your little one to hold!

Stainless steel cup

Great cup! Have been using the sippy cup with my 13 month old and he loves it. We started with the straw at 11 months old, but became obsessed with pulling it out

Great sippy cups!

I bought x2 sippy cups, they're great. I was looking for a plastic free option. I like the fact that they're light, leak free, come with a 3 in 1 lid and have handles so my baby can hold the cup easily. Also love that I'm supporting an Australian brand too!

Good design and quality

I purchased the cup with silicone lid and metal plate for our 12 month old and he finds them easy to use and it is a good size for his age. The spout is more leak proof than your standard plastic sippy cups which is a bonus when they tip it upside down! Great product and would definitely purchase more products in the future.

Best cups!!

I go the 3 in 1 sippy cup for my 11 month old son and absolutely love it! Highly recommend. I love that it’s easy to clean, even the straw. I also love that the lid comes off so he can drink from regular cup with handles. It grows with them. I wish I would’ve gotten this cup earlier.

So delighted

I bought two sippy cups - one for home & one for grandparents (a soft rose pink & the soft sage green colours) and they are fabulous. Such a brilliant design to prevent spills if they fall, with both lids. I’d love to get a whole range of items if I could! Beautiful form & function. Thank you so much!

Great toddler cups

I transitioned my 15 months old to the stainless steel and silicone straw cup and he took to it right away. It doesn’t spill at all and is a nice quality. Glad I bought them! Thanks Greenvyne

Cherie

Great product! Sippy lid doesn't leak and my 11month old has no issues holding and using it herself.
Only thing is when she drops it onto the floor from her highchair, the lid pops off easily and water spills everywhere.
Having said that, it doesn't bother us much as we love that it's stainless steal, easy to clean and comes with the different lid/straw options as bub grows.

Sippy Cup for the Elderly

Was looking for van alternative to the horrible plastic sippy cups in Aged Care.

Bought a green one for my dad. Works great!

Great cups

I’d been looking for something to replace my plastic sippy cups and these are great. The silicone handles make them easy to hold and prevents any thuds if they’re dropped. The silicone lids fit nicely and create a perfect seal so there’s no spills. I also really like that they come with a selection of different lids. Overall I’m really happy with these!

Is the Greenvyne sippy cup leak-proof?

Yes! Our new upgraded design features a leak-proof sippy lid and a leak-proof straw lid with a valve straw. This means no more messy spills or puddles on the floor, even if the cup is tipped upside down or dropped.

Can I use it for thick smoothies?

Yes! The wide straw handles thicker drinks with ease — just rinse straight after use so nothing clogs.

Are these products safe for babies and toddlers?

We craft our products from high-quality, 18/8 (304) food-grade stainless steel. This is a durable material widely chosen for family tableware because it is easy to clean and does not retain odours or flavours from previous meals, making it a practical choice for everyday use.

What are the top-rated sippy cups for toddlers in Australia?

The most recommended stainless steel sippy cups for Australian toddlers share three characteristics: a transition system that grows with the child rather than requiring replacement at each developmental stage, food-grade 304 stainless steel construction rather than plastic or aluminium, and FDA or LFGB certified silicone components rather than uncertified silicone with fillers.

The Greenvyne 3-in-1 stainless steel transition cup covers all three: a spout lid for early sipping from around 4 to 6 months, a straw lid for toddlers from around 9 to 12 months, and an open cup top for independent drinking from around 18 months. It is made from 304-grade stainless steel, uses FDA-certified platinum silicone on all components, and has been independently tested to EN 14372, the European standard for children's feeding utensils. It ships Australia-wide from Melbourne.

Why is there water under the silicone base of my stainless steel cup?

It’s normal for a small amount of water to get trapped under the silicone sleeve or base after washing. Simply remove the sleeve and let both parts air-dry fully before putting them back on. This prevents moisture build-up or odour. All Greenvyne cups use food-grade 304 stainless steel and FDA & EU certified silicone, designed to be safe, durable, and easy to clean.

Will the sleeve slip?

Nope. We moulded a tiny internal ridge so the silicone hugs the steel even when wet.

Logo update

We’re transitioning to our new logo. You may receive this product with our previous or updated engraving. Same product, same materials, and the same quality you trust.

What comes in the box with the sippy cup?

Each Greenvyne 3-in-1 sippy cup includes the stainless steel cup body with dual
handles, two interchangeable lids, the soft silicone spout lid and the straw lid with valve straw, and arrives in plastic-free packaging.

The 2-pack bundle includes two cups in your choice of colours for $49.95, with all components included for each cup.
