This is a rare, handcrafted bangle made from the baleen (whalebone plates) of a fin whale (Nagasukujira). It is a one-of-a-kind piece that utilizes the natural flexibility of the material and features a twisted design. It combines strength and flexibility, and is characterized by its light and comfortable fit. 【Main Specifications】 • Material: Fin whale baleen (legal stock) • Finish: Hand-polished, twisted • Size: Inner diameter approx. xxcm (equivalent to sizes 4-5) *Elastic • Color: Black to dark brown (variations exist due to the natural material) • Weight: Extremely lightweight (you'll forget you're wearing it) 【Special Notes】 • This item is handcrafted, so there are slight individual differences compared to mass-produced machine-made products. • Please understand that minor patterns and color variations are inherent to the natural material. • It has flexibility and can be gently opened and closed when worn, but please avoid applying excessive force. 【Background】 Baleen was once used in weaponry, musical instruments, and decorative items, but its distribution is now extremely limited.
