Product Description: Genuine Leather Color: Natural Thickness: Approximately 2-3mm Ring size varies depending on the leather thickness. Please understand this as a general guide. Vegetable-tanned leather was used. Cut and hand-stitched by hand. This leather allows you to enjoy the aging process. Waxed thread is used for hand-stitched leather. This thread is coated with wax and does not break easily. The final knot is sealed by melting the wax with fire. This may cause some blackening. Are you with metal allergies looking to enjoy rings? There may be some size discrepancies. We recommend purchasing a size larger than usual. Shipping will be the most affordable option. There is no compensation for standard or non-standard mail.
