Genuine Leather Ring [Tochigi Leather] Sizes 16-18 [Product Description] Genuine Leather: Tochigi Leather Co. Thickness: Approx. 2mm Ring size will vary depending on the leather thickness. Please understand this as a general guideline. Finished by hand cutting and hand sewing. This leather can be enjoyed as it ages. Hand-sewn leather uses waxed thread. This is thread coated with wax and is difficult to break. The final knot is secured by melting the wax with a flame. At that time, some black charring will occur. Why not enjoy accessorizing your fingers even if you have metal allergies! There may be size variations. We recommend purchasing a size larger than usual.
