I am using chain BOX1.0DC. Comes with an adjuster of approximately 5.5cm, so the length can be adjusted. The listed length is from the end of the trumpet to the first frame of the adjuster, and is the length when worn at its shortest length. *Chain length may vary by +-5mm. *The shape and size of the pieces may differ slightly depending on the lot. *As this is an accessory, the color may change to reflect changes in fashion. Also, during the processing process, color shading may occur without prior notice. Please note. (Some parts may differ in color from other parts.)
