Moomin Key House This is a key holder that can be stored in the Moomin House. There is a magnet on the back of the house, so it sticks to iron doors. It can also be attached with a hook. Attach your keys to the Moomin key holder and store it in the house when you get home. It's very cute. This is an old item, and I don't think it's sold anymore. The outer plastic box has fine scratches, but the contents are new and unused.
