A new twist on reusability.
KeepCup is finally ready to present Helix, a completely twistfit leakproof thermal mug. The mug is made of double-walled stainless steel. The idea behind Helix is the "cup-to-bottle" system, which allows you to convert your mug into a thermal bottle. In this kit, you get a complete set with a sealed mug and a bottle top, both made of double-walled steel.
Complete set with a thermal mug and both a twistfit lid and a bottle top. The capacity with the bottle top increases by approximately 2 dl, making it 0.5l for the 12 oz and almost 0.7l for the 16oz.
