We used a 2mm diameter domestic round leather cord. You can use it by threading your favorite pendant top, etc. (The part to thread through needs to be about 3mm in size.) ・We will make it to your specifications, such as the color and size of the leather. Please let us know your preferences after winning the bid. (Within 50cm) ・You can order the length, so you can use it as a choker if it's short, or as a pendant if it's long. (The length includes the fittings, and in the case of an adjuster type, the length can be adjusted by about 5cm.) ・Choose the leather cord color from black, dark brown, natural, or brown, and the metal fitting color from silver, gold, or antique. The color of the leather cord may vary slightly depending on the arrival time and the environment in which you view it. Also, black and dark brown are similar colors. ・Choose the type of fitting from adjuster, small plate can, or large plate can. If you have multiple requests or want to add length, please let us know in the comments.
