I bought this when I transferred schools, but I only used it for a short time. The cover shows some signs of use, but I think the recorder itself is clean. I have disinfected it 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.
