All Aboard MegaPack All aboard! This adorable set of wall stickers allows you to create a custom train track and train on any wall or smooth surface. Children will love mapping out their own track, hooking up the train cars, and decorating with the additional red, yellow, and green dots. It’s so much fun to decorate with our MegaPacks! And like all RoomMates, the decals can be repositioned at any time, so there’s no need to worry about sticky residue or damage to your walls. Great for any junior train enthusiast!
