DISHWASHER SAFE: Our stainless pints are dishwsher safe and our inks are Heat-Set and will not fade. However, we thoughroughly recommend washing by hand, as this is the safest and most effective method for all stainless pints. If washing in a dishwasher, be sure to keep all mugs from touching each another object in the dishwasher to avoid scratches. NEVER place staineless pints on the bottom shelf of the dishwasher. Do NOT scratch the print with metal objects.
