This is a Protec alto saxophone case, originally priced around 40,000 yen. It's very lightweight, durable, and a great case. I purchased it online and tried putting my instrument in it, but the size didn't fit, so I'm selling it. I only tried it once and haven't used it since. A Yamaha alto saxophone (YAS-875EX) fit perfectly. It's been stored in a large bag, so there's no need to worry about dust. I don't have any pets. - Color: Black - Interior: Soft blue material - Type: Backpack-style alto saxophone case - Straps: Adjustable shoulder straps - Pockets: Exterior storage pocket. Can store sheet music, etc. - Design: Slim design Thank you for looking!
