This is a YAMAHA YTR-2310 trumpet. It's a classic Yamaha model made in Japan, popular with beginners and students. I purchased it about 35 years ago, and it has been in long-term storage. I have confirmed the following operations for this listing: 【Condition】 ・Sound production confirmed (I have not checked the fine tone or pitch) *I have not performed long-term playing or professional adjustments. ・All three pistons operate smoothly. ・All tuning slides have been confirmed to move. ・No major dents are visible. ・There are minor scratches and dullness due to aging. 【Accessories】 ・Original hard case ・Mouthpiece (shows signs of use and discoloration / playable) * The mouthpiece has been washed with neutral detergent and thoroughly dried before listing. However, as individual perceptions of hygiene vary, those who are sensitive or planning to purchase a new one can request shipping without the mouthpiece. If you wish to do so, please let me know via the transaction message after purchase. (※There is no price change depending on whether or not the mouthpiece is included) * There is a faded area on the outside of the case where a name was erased (please check the photos). I have not played it for a long time, so I cannot provide an evaluation of playing technique or fine adjustments. Please purchase with the understanding that this is a used item and will be sold as-is. Recommended for beginners and for the upcoming school year and club activities season. There is a name written on the case, but it is not shown in the photos to protect personal information. I will carefully pack it with cushioning material and ship it via Rakuraku Mercari or Yu-Yu Mercari.
