I bought this when I transferred schools, but I ended up only using it for a short time. The cover shows some signs of use, but I think the recorder itself is clean. It has been disinfected as much as possible. The part that goes in the mouth is smooth with no bite marks. Individual perceptions vary, and this is a used item, so I'll sell it to someone who doesn't mind the small details. 【High-Quality Tone】 YAMAHA soprano recorders offer excellent sound quality, suitable for a wide range of players from beginners to advanced. 【Convenient to Carry】 The included case makes it easy to carry and store. 【Easy Maintenance】 A cleaning stick is included for easy maintenance. - Brand: YAMAHA - Model: YRS-312B - Type: Soprano Recorder - Material: Plastic - Accessories: Case, cleaning stick - Color: Black, White - Country of Manufacture: Indonesia Thank you for looking.
