We all know the importance of staying hydrated, or maybe you just can’t go without your morning coffee.

The problem we are all facing is that once our mug is empty, it just takes up so much space and it really does not fit into our purse, pockets, car door…

This problem has been solved when this amazing FDA approved, BPA free silicone technology came into existence.

Known for its durability, amazing color contrasts and a soft touch, this material is now the back bone of our foldable mug.



It holds more than ½ liter (550 ml) and can be used for freezing cold or boiling hot beverages.

When fully folded, its size is only 4 inches x 1.3 inches (10 cm x 6 cm) and it will fit even into your pants or jacket pocket.


4 Different Sizes In One Mug:


Use it for your espresso in the morning by folding it to a 250ml size. Use it for your tea break by folding the lower part of the mug and opening the upper one. Use it in the afternoon when you can put your protein shake in there for your workout or fill it with water for your afternoon walk, by fully unfolding it to its full capacity.

Main features:

      ✔️ Environmental friendly BPA-free material
      ✔️ FDA approved
      ✔️ One of a kind non scratch material
      ✔️ High temperature resistance
      ✔️ Freezing temperature resistant
      ✔️ Antifouling
      ✔️ Dishwasher safe
      ✔️ 4 adjustable sizes
      ✔️ Climbing buckle included to hang on backpack
      ✔️ Thread seal design prevents leakage
      ✔️ Temperature safe holding ring (even if content is hot or cold, you can hold the mug)


    How To Use Your MTS Foldable 550ml Mug?

    When you get the mug, we would suggest you to boil a cattle of water and pour it in to sterilize it.  

    You should normally do this with every mug you buy in a store or online, but regular cheap material cannot resist high temperatures, so manufacturers do not suggest it, even though it is necessary.

    After 5 seconds pour boiling water out of the mug and let it dry, or wipe it with a soft cloth.

    Your new Mug is ready to become your best friend when at home, strolling through park, going on a jog or having your morning coffee at your office.
