◼️TROIKA Troika 3-Ring Keyring (Piano Forte) KR12-04/CH Manufacturer: Troika Japan Brand: TROIKA (Troika) Contents: 32g Material: Zinc alloy This is a keyholder with a musical motif. It features charming charms of Beethoven, a piano, and a treble clef. Although it is unused, the box has some signs of aging, so I would like to offer it to someone who understands this.
