Thank you for viewing. Before purchasing, please leave a comment to confirm the specifications and stock availability. This is a domestically produced guitar strap made by us, using approximately 4mm thick black Japanese vegetable-tanned leather. The material is high-quality Japanese vegetable-tanned leather, which is very durable and firm, yet also flexible. The color is a slightly glossy black, with a deep dye that minimizes unevenness while taking advantage of the leather's surface. The dye penetrates the core, so the edge (cross-section) is also black. The shoulder pad is 6cm wide and 31cm long, and the belt part is 2.5cm wide. Undyed pig suede leather is attached to the back of the shoulder pad to prevent slipping. The stitching color around the perimeter is basically black, but it can be changed to white, etc. Double stitching is also available for an additional 500 yen. Please let us know before purchasing if you would like to make any changes. The buckle is basically black chrome. It can be changed to silver, antique color, or a domestically made brass roller (+300 yen). Please let us know before purchasing if you would like to make any changes. The edges (cut surfaces) of each part and the back of the belt part are all smoothed by hand to prevent fraying. Length: L size 120-140cm It can be adjusted in 2.5cm increments with the buckle. We can also make longer sizes, so please consult us if you need one. Please choose either a general 7mm slit hole or a 10mm hole for Schaller/Dunlop lock pins for the attachment holes. Shipping is planned via Kuroneko Yamato Mercari Compact, and the packaging will be simple, using a zip lock bag. Thank you for your understanding.
