Calumet & Hecla 70-Tonner #210

70 Ton General Electric #210 of the Calumet & Hecla

All 11oz and 15oz ceramic mugs are microwavable and dishwasher safe.  While they are very durable, they can be scratched by hard metal edges.  Avoid putting them next to silverware in the dishwasher.

Tumblers are dishwasher safe, but NOT microwavable due to stainless steel construction.  They are a two-piece, double-wall design and will keep your beverage hot or cold for several hours.
