Blue thread Silver-colored hardware are used. Nubuck leather is a type of leather that can be expected to change over time. Applying oil will increase the luster and soften it. Also, the color will change with exposure to sunlight. With this leather, you can expect a change to a dark navy blue (the original color will mix with brown). From cutting to processing, assembly, and sewing, everything is done by hand. Due to being handmade, there may be slight errors, but there are no problems with use. ☆Custom orders on Mercari are no longer available.
