25cm x 25cm I purchased this new for my child, but they didn't seem to like it and didn't play with it much. [Tobacco/Pets] - No smokers - I have one short-haired cat. (I will check to make sure no hair gets in, but it may be unavoidable due to static electricity.) - Please be careful if you have a cat allergy. [Packing/Shipping] - In principle, I will ship via the cheapest anonymous method. - I will use recycled materials and pack compactly. - There may be changes between Yu-Yu and Raku-Raku shipping methods without notice. If you have a preferred shipping method, including date and time specifications, please consult with me in the comments before purchasing.
