This is a zippered mouthpiece pouch for tenor saxophone mouthpieces. The internal dimensions are 5cm x 4cm x 12cm. It's sized to hold a tenor saxophone rubber mouthpiece with a large ligature attached, and it opens and closes with a zipper for easy storage and removal. There's a sling loop at the top, so you can hang it somewhere with a carabiner or similar. A name tag for specifying the type is also included. (I forgot to attach it in the photo, but it will be included with the product.) The outer fabric is a cushioned quilted fabric. The inside is made of cotton-based fabric. Also, to avoid scratching the mouthpiece, the zipper is made of plastic. Please understand that this is handmade before purchasing. Please note that the price may differ from previously sold similar products, as the design, materials, and fabrics are improved from time to time. The price has been reset due to the increase in postal rates. The mouthpiece is not included. The color may differ slightly from the actual product in the photos.
