We have designed our on-the-go tumbler with kids in mind. It holds 0.25 L and has double walls with vacuum insulation. It is made of high quality, food grade 18/8 stainless steel and comes with an anti-slip pad on the bottom. TEMP Tumbler keeps your drinks icy cold or hot for hours. It comes with an easy-to-sip stainless steel straw with a flexible silicone tip and a multifunction lid that has a flip opening for easy drinking and also a hole for straw-drinking. The straw hole is leakproof when the straw is not used. A cleaning brush for straws is included. The TEMP Tumbler is extremely robust and can be used over and over again, which makes it a first hand, sustainable choice on the go. Perfect for the kids to have in the playground, on an excursion or during a trip. All parts of the tumbler are of course non-toxic and don’t contain BPA- or phthalates. Stainless steel also means no retention or imparting of flavours. Wash by hand. Not for use in a microwave or freezer.
