This is an all-leather strap featuring musical notes. It's made by layering and stitching together three pieces of 1mm thick cowhide. Soft leather is used for the first and third layers, and a firmer cowhide is used as the core for the second layer. It's about 3mm thick, but has a very soft finish. The musical notes are also made of soft leather, with pearl white used to match the pastel pink sheen. The stitching is double, using size 20 thread. Color: Pink Material: All leather Width: Approximately 7.5cm Thickness: Approximately 3mm Length: Adjustable from approximately 87cm to a maximum of 118.5cm. Regarding adjustment, the length adjustment holes on the main A part are made with some leeway, but the adjustment holes on the B part are made tight. The width is made wide, so I think it can be used for both guitars and basses. This is my first time using soft leather, and it turned out well. As it is a natural material, there may be original wrinkles, scratches, and stains. Please understand this before purchasing. Thank you for viewing. Thank you very much.
