How to keep the bamboo cup from cracking

There is water in the bamboo cup all the year round. If the cup wall is kept dry, it will not crack easily.

Reasons for cracking of bamboo cups:

First, the bamboo cup wall is too thick, and the cup will crack when it is dry.

Second, if the bamboo skin is not removed, it will crack.

Therefore, when choosing a bamboo cup, you should choose a cup with thin wall and no bamboo skin.
