Review on Dewel Classic Stackable BPA-Free Material by Henry Brown

Bought as a birthday present for my nephew. He is very fond of Rubik's Cubes and can solve them very quickly. I thought he might also be interested in learning how to quickly place and unfold these cups. I also thought it would be fun to do them with friends. I give 4 stars because he told me that one of them broke within a few days of use. Shortly after letting me know that I had received an email from the seller asking if I was happy with my purchase and when I explained to them that one mug was already broken they offered to take me send a new set as a replacement. I appreciate the customer service and their willingness to make things right.
