A new twist on reusability.
KeepCup is finally ready to present Helix, a fully twistfit leakproof thermal cup. The cup is made of double-walled stainless steel. The idea behind Helix is the "cup-to-bottle" system that allows you to convert your cup into a thermal bottle. In this kit, you get a complete set with a sealed cup and a plastic bottle top with a practical loop.
Complete set with a 300ml thermal cup and both a twistfit lid and a transparent bottle top. The capacity with the bottle top is 0.5L.
