The slot-in paper inserts kept the mess contained, and my niece loved swapping designs halfway through. The box itself was sturdy enough to gift, too.

The removable paper inserts made it easy for my niece to switch designs without making a mess, and the box it came in was cute enough to gift as-is. She loved coloring the mug while watching her show, and the 8cm size is perfect for little hands.
