This is a zip-up mouthpiece pouch for tenor saxophone mouthpieces. The internal dimensions are 5cm x 4cm x 12cm, and the color is ivory. 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 is also included for specifying the type. The outer fabric is a cushioned quilted fabric. The inside is made of cotton-based fabric. Also, the zipper is made of plastic to prevent scratching the mouthpiece. 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 mouthpiece is not included. The color may appear different from the actual product in the photos.
