I love these tumbers so much, I have one that I use all the time! I was so bummed when my white glaze decided to just not cooperate on these. The whole interior is coated, but the glaze has a very inconsisten and clumpy appearance on the inside. I have put these on sale to account for the glaze issues, but they still function well as a cup!
 
These tumblers hold 16 oz of fluid and the carved patter makes them fun to hold!
 
A note about handmade pottery:
 
These are hand thrown and glazed by me, so there are some slight variations  and imperfections within them.
