This is a clear plastic butter case that comes with the purchase of a mabe refrigerator. It is new, unused, and has been stored at home. It seems that it costs 1,100 yen for shipping if you purchase it separately from mabe, so I think it's a good deal for those who are looking for one. Thank you for your consideration. - Model Name: WR01G00623B - Color: Transparent - Material: Plastic - Price: ¥2,200 (tax included)
