Genuine Leather Ring, Sizes 19-21, Leather Ring [Tochigi Leather] [Product Description] Genuine Leather: Tochigi Leather Co. Color: Sky Blue, Light Blue, Blue Thickness: Approx. 2mm Ring size will vary depending on the thickness of the leather. Please understand this as a general guideline. You can also thread it onto a necklace chain and use it as a sunglass holder. Made with vegetable-tanned leather. Finished by hand cutting and hand sewing. This is a leather that can be enjoyed as it ages. Hand-sewn leather uses waxed thread. This is thread coated with wax and is difficult to cut. The final knot is secured by melting the wax with a flame. This may cause some black charring in that area. Why not enjoy fashionable rings even if you have metal allergies! There may be size variations. We recommend purchasing a size larger than usual. Shipping will be via the most economical method. There is no compensation for registered or unregistered mail.
