Do-It-Yourself Heart Mug is a great way to say "I love you"! Great for birthdays, anniversaries, holidays, or just because. Ships with a black Pebeo pen so you can personalize the mug.
The revolutionary pen works just like a marker. Wash off mistakes with a damp sponge. Once the markings are dry, fire your mug in any conventional oven at 300 degrees for 35 minutes. It's permanent, dishwasher, microwave and food safe! Instructions included.
