Please understand this as a general guide. Cut and finished by hand & hand-sewn. This leather allows you to enjoy the aging process. Hand-sewn leather uses waxed thread. This thread is coated with wax and is not easily cut. The final knot is sealed by melting the wax with fire. This may cause some black scorching. Why not enjoy fashionable rings even if you have metal allergies! There may be some size discrepancies. We recommend purchasing a size larger than usual. Material...
