This is a flute case cover from NAHOK, known for its waterproof materials. The inner dimensions are approximately 40cm x 10cm. It does not have a shoulder strap, so it can be carried by hand or over the shoulder. The leather on the hand-carry portion, which is prone to wear and tear, is in good condition. It should also fit shakuhachi flutes and recorders. It may be a discontinued or overseas model, so those in good condition are considered rare. Current models cost around 27,000 yen. Exterior: German-made Super Tilt (lightweight and durable fabric with waterproof, UV, and stain-resistant processing) Interior: European-made Super Heat Insulator (special temperature regulation function & shock-absorbing material) Zippers: Japanese water-resistant zippers
