■ GALAXY Trombone Straight Practice Mute (for training) ★ Almost unused, so the cork parts are clean with no signs of wear. ★ There is some slight roughness in the paint on the aluminum part. ★ Although it's for trombone, the size fit my flugelhorn, and when I tried it, it increased the resistance, but it was effective for muting, and the sound was significantly suppressed, allowing for practice at night. ★ Will be shipped via Yu-Yu Mercari delivery service.
