These are "Sasatome (Kohaze)" made from natural bamboo, carefully cut one by one by hand. In recent years, as plastic ones have become more common, please experience the appeal of rare bamboo products. ── Product Features ── Handmade by artisans: The texture of the bamboo is utilized, and it is carefully shaped and polished. Rare natural material: Bamboo products are becoming increasingly difficult to obtain commercially. They have a warmth and high-quality feel that plastic cannot replicate. Versatile use: Can be used not only as a fastener for shinobue (Japanese flute) bags, but also for Japanese accessories, as an accent for drawstring bags, as parts for handmade accessories, and more, depending on your ideas. ── Dimensions ── Precise measurements (using calipers) have been taken, but please allow for slight individual differences due to being handmade! Length: Approximately 41mm Width: Approximately 7.5mm Thickness: Approximately 2mm Hole diameter: Approximately 4mm ── Regarding Purchase ── Appearance of natural materials: Because natural bamboo is used, the color of each piece is different. In addition, there may be natural spots and scratches that occurred during the growth process, but please enjoy them as a unique "flavor" of the natural material. Regarding discounts: We do not accept price negotiations for these handmade masterpieces that take time and effort to create. Experience the natural feel and strength of bamboo, which plastic cannot offer. Why not add a touch of genuine quality to your creations and important tools?
