Was looking for van alternative to the horrible plastic sippy cups in Aged Care.
Bought a green one for my dad. Works great!
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!
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.
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!
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.
Yes, it's designed to be highly spill-resistant. The new valved straw and sippy spout are designed to minimise spills from tipping. A second, free-flow straw is also included for thicker smoothies, which is not spill-proof.
Yes! The wide straw handles thicker drinks with ease — just rinse straight after use so nothing clogs.
Nope. We moulded a tiny internal ridge so the silicone hugs the steel even when wet.
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.
While steel reflects microwave energy, some purpose-designed stainless-steel containers can be used in microwaves under strict guidelines. Greenvyne bowls and plates are not microwave-safe. To warm food, transfer it to a microwave-safe glass or ceramic container.
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.
