Thank you for viewing! This is a tenjin bag for a medium-neck or thick-neck shamisen. It's made to fit the tenjin (headstock), so it can be used for tenjin covers up to size 22, as shown in photo 6. You should find a number written on the back of your shamisen's tenjin cover; please refer to that. If there isn't one, measure the back of your shamisen's tenjin with a ruler. It should fit if your shamisen's tenjin is 6.6cm or less. The opening has elastic, making it easy to put on the tenjin, and it's designed so the tenjin bag won't slip off easily. Originally, it was made by deconstructing a single kimono. As you can see from the photo of the fabric, it depicts the scenery and people of the Fifty-three Stations of the Tōkaidō. It's made of very beautiful silk fabric. Why not consider it? (Materials) Outer fabric: Silk Lining: Silk #Shamisen #TenjinBag #TenjinCover #Nagabukuro (Long Bag)
