This is the Kodomo Challenge Pocket "Uta to Hanachan Osewa Set." I received a used one from a friend and am already using it, so I am selling a new, unused one. The care cards appear to be made of thick paper. Would this be suitable for your child's pretend play? Although it is new and unused, please refrain from purchasing if you are concerned about home storage. Also, I have a dog indoors. I will take great care when packaging, but there may be some hair mixed in. If you have allergies or are concerned, please refrain from purchasing.
