Purchased new and used a few times in an orchestra. There is a feeling of use due to the leather material. Please note that we cannot accept returns. The following is quoted from the internet: This is a leather hand rest for trombones, used for non-slip purposes. It can also be used to prevent rust caused by sweat and wear. It is a set for wide slides, left and right. ■ For wide slides ■ Made of leather, string type ■ Color: Black ■ Set contents: Right hand x 1, Left hand x 1 ※ Because it is made of leather, it may get stuffy in the summer or after long hours of playing. To protect the lacquer and plating, it is recommended to loosen the strings and wipe off the moisture and dry it after each performance as much as possible.
