40 LAYER! Hybrid Flow- Black and White with 16-Color Rainbow Inserts- Carved In & Out - Functional Fine Art Tumbler

Available from POTS when we last checked. Sold from the shop’s own store; the price there is the one that counts.

A pretty wild specimen, pushing process to the limit. 7oz dishwasher and microwave safe glazed interiors and buffed ceramic exteriors. PLEASE NOTE: The cup will become hot when filled with hot liquid. Please use for hot beverages with caution.
