Can the water cup made of bamboo tube be used?
There is no obvious benefit in holding water in bamboo tubes, but the water will have the fragrance of bamboo. Nowadays, water cups are better than glass, and there are no heavy metals. It is difficult to guarantee that there is no problem with the paint of the bamboo cup. Generally, unless it is produced by a very formal manufacturer that meets the national production standards, it seems that there is no professional production, so it is recommended not to use it.
