Pokemon Moncolle EX Wobbly Monster Ball Case - Rare Item. This is an official Moncolle merchandise item released approximately 10 years ago. It's a storage case, but you can also expand your world and play with the wobbly tower feature. There are no malfunctions, but since this is a used item that children played with, there are signs of use and scratches. Please refrain from purchasing if you are extremely concerned about the condition. Please also check my profile.
