Yamaha YCL351 B♭ clarinet. Before listing, balance adjustments have been made, so you should be able to use it with confidence after winning the auction. The mouthpiece is a Vandoren 5RV, purchased separately after buying the main unit. It has been used infrequently and is still in good condition. Please refrain from bidding if you are looking for a perfect item or are overly concerned about minor details, as it has been stored at home for a long time. Thank you.
