Thank you for viewing! (^ ^) This is a "Hat Bag" purchased from Hobbyra Hobbyre. The color is a deep brown, like dark chocolate. You can create a wonderful bag by using this as a base for embroidery or decorating with knit motifs, and then attaching handles. It was featured in Naoko Shimoda's book, and a kit was also released by Hobbyra Hobbyre. Of course, it can also be used for hat making. Opening: Approximately 76cm, Height: Approximately 26.5cm It's the size of a typical adult hat. Made of 100% wool felt, it's thick and sturdy, with a thickness of 1-2mm or more. It was new and unopened, but I opened it for inspection. There are no problems, and it's in beautiful condition. When shipping, I will only send the product and its packaging, without the cardboard box, to fit the Nekopos size. Please understand that this is a self-inspection and a home-stored item before purchasing. Thank you very much! (^ ^) #NaokoShimoda #HatBase #BagBase #WoolHatBody #HatBody
