Although the size isn't listed, this item is smaller than the 13cm shoes that my child has outgrown. I purchased this item new and used it for daycare. Items used frequently may have pilling or loose threads. I stamped my child's name on the inside of the rubber. [Smoking/Pets] - No smokers - I have one short-haired cat. (I will check for cat hair, but it may still get mixed in due to static electricity.) - Please be aware if you have a cat allergy. [Packaging/Shipping] - In principle, I will ship via the cheapest anonymous method. - I will use recycled materials and pack compactly. - Shipping may be changed from Yu-Yu to Raku-Raku without notice. If you have a preferred shipping method, including date and time, please consult with me in the comments before purchasing.
