This bamboo cup specially made by Al Wheatley also known as Chop Chop stands 3 7/8” high with a mouth diameter of 3”. It is not common to find one of these original cups and this one functions just as it should. Use your own chop balls.  Includes drawstring bag as pictured.

Condition the Bamboo is splitting in a few areas which can be natural since it is Bamboo but cup is stable, the green bands were probably put on not just for decoration but because of the splitting.
