These blank ceramic mugs are perfect for creating professional-looking mugs in just a few minutes. This stackable set contains 4 blank mugs and 4 matching gift boxes. With a smooth ceramic finish and straight pressing surface, you'll get flawless transfers every time. Personalise your mug with a name, logo, inside joke or favourite quote using Infusible Ink™ products and the Cricut Mug Press™ does the rest. Unlike an iron-on transfer or vinyl application, where artwork is attached to a base material using adhesive, your Infusible Ink heat transfer becomes one with the mug itself. The results are permanent, seamlessly smooth - and dishwasher and microwave safe. ** Carefully follow instructions at cricut.com/make-mugs. WARNING: Extremely hot immediately following heat-transfer process. Adult use only.
