The 16-oz. Do-It-Yourself Classic Mug is perfect for kids of all ages (some supervision required) to commemorate a birthday or graduation, or just to show love to someone special. It ships with a ceramic pen that works like a marker; mistakes can be removed with a damp sponge. Once signatures are dry, kids, with the help of their parents, can fire their mugs in a home oven at 300 degrees for 35 minutes. It's permanent and dishwasher, microwave and food safe, and comes in purple and green. Launch date: Spring 2006.
