These mugs are hand-enamelled so each one is different. Dimples and dots are natural and add to the unique charm, but this can affect the printed result in unexpected ways. Designs with simple elements and no block colours tend to offer the best results.
Enamel mugs are not dishwasher or microwave safe. To prolong the life of the product we recommend washing with a non-abrasive sponge.
Keep away from open flames! They're traditionally an outdoor/camping product so we understand the temptation, but again; to prolong the life of the product we recommend treating it with love.
