Pure 304 food-grade stainless steel cups. Designed with thick walls to keep warm drinks warm and cold drinks cool, while remaining comfortable for little hands to hold.
Zero plastic, zero coatings. The 300ml size is perfect for both kids and parents. Packed in a cotton travel pouch inside a compostable courier bag.
Finding a good cup was surprisingly hard. Plastic started smelling like the dishwasher, and silicone made water taste funny. We wanted something pure that kept drinks fresh and could actually survive being dropped. Stainless steel was the obvious answer.
Keri - founder and mum of Leo and SunnyPure 304 stainless steel — no BPA, no microplastics, no coatings. Safe for kids and adults.
Steel is non-porous — it absorbs nothing. Looks and smells as clean in year three as it did on day one.
Thick walls provide natural insulation. Cold drinks stay colder, warm drinks stay comfortable to hold.
The 300ml size works for little ones and adults alike. One set, sorted.
Won't crack, warp, or degrade. Still going strong long after the plastic cups are gone.
