Stainless Steel Cups & Sippy Cups

Our current drinkware range includes a 3-in-1 stainless steel sippy cup in 220ml with four colour options and a 2-pack, 4-pack and 6-pack bundle, available in both a new and classic edition, and a 350ml stainless steel cup with a non-slip silicone grip available in a 4-pack multicolour set and classic version without the silicone grip. Both products are made from food-grade 304 stainless steel, completely BPA-free, dishwasher safe, and available to ship Australia-wide. More drinkware products are added to the range regularly.

Our 3-in-1 sippy cup is designed to cover three developmental drinking stages. The spout top is suitable from approximately 4 months, as babies begin to transition away from bottle feeding. The straw lid is suitable from around 9 to 12 months, as toddlers develop the suction control needed for straw drinking. The open cup top removes the sippy cup component entirely and is suitable from approximately 18 months as children develop the coordination for open cup drinking. The cup grows with the child rather than being replaced at each stage, which is the point.

Yes. Food-grade 304 stainless steel is one of the most chemically stable materials used for food and drink contact in the world. It is completely inert, it does not leach
chemicals into liquids, does not react with acidic drinks like juice, and contains no BPA, phthalates, coatings or dyes. It is the same material used in baby food processing equipment, hospital feeding systems and commercial kitchen equipment worldwide. For our products designed for children under 36 months, we test to EN 14372:2004, the European standard for children's cutlery and feeding utensils, which covers both mechanical and chemical safety. Full documentation is available on our Quality and Safety page.

Yes. All Greenvyne stainless steel cups and sippy cups are dishwasher safe. Top rack placement is recommended for the stainless steel cup bodies and sippy cup components, straw, spout and lid, to extend their lifespan. The silicone grip sleeves on the 350ml cup are dishwasher safe and will last longer with top rack placement. If you live in a hard water area, a quick wipe with a dry cloth after the cycle prevents water spotting on the steel surface.

Both versions of the 3-in-1 sippy cup share the same stainless steel body and the same three-stage lid system. The new edition features an updated lid and straw design and is available in four colours: Sage, Peach, Cocoa and Cream, with a 2-pack bundle option. The classic edition is the original version of the cup, available only in Sage. If you already own the classic and want a second cup, both versions are fully compatible with the same replacement lids.

Our 350ml stainless steel cup is suitable for both cold and warm drinks. It is not a vacuum-insulated thermos, so it will not keep drinks hot for extended periods, but it is completely safe for use with lukewarm beverages, including warm milk, cocoa and herbal tea. The non-slip silicone grip provides some insulation against heat transfer to the hand. The 3-in-1 sippy cup is designed primarily for cold and room-temperature
drinks. We do not recommend filling the sippy cup with boiling liquids.

Yes. All Greenvyne stainless steel cups are completely BPA-free, as is all food-grade stainless steel by nature; the concern around BPA relates specifically to certain types of plastic, not steel. Our cups contain no plastic in the steel body or rim. The straw and spout components on the sippy cup are made from platinum food-grade silicone, which
is also BPA-free. The silicone grip on the 350ml cup is food-grade silicone, BPA-free. There is no plastic anywhere in contact with your child's drink.

The 350ml stainless steel cup is a versatile open cup suitable for children from approximately 18 months as they transition away from straw cups. It works well for toddlers learning to drink from an open cup, for school-aged children, and equally for adults as a daily drinking cup or smoothie cup. At 350ml, it is a practical all-day size, larger than a small children's cup but compact enough for a park picnic or camping trips. The non-slip silicone grip makes it secure in smaller hands while still being a natural fit for adult hands.

Stainless steel water bottles for kids and adults are coming to the Greenvyne range. Both single-wall and insulated options are in development across a range of sizes for different ages and use cases. Join our email list or follow us on Instagram to be the first to know when they are available.

Insulated cups for coffee and smoothies are in the Greenvyne drinkware roadmap. They are designed to work as part of a complete stainless steel drinkware system alongside our existing cups and upcoming water bottle range. Join our email list to be notified when they launch.

Currently, a 220ml sippy cup and a 350ml cup with a silicone grip. A larger adult cup size, followed by a water bottle and an insulated cup range for kids and adults. The goal is a complete stainless steel drinkware system across all ages and daily use occasions.
