As a professional horsehide product brand, Double Helix always selects materials according to strict standards. We always select the raw hide of large Polish horses, with a thickness of 1.2mm-1.4mm. Through the improvement of traditional Japanese vegetable tanning, repeating tests on the tanning time, gloss, color and so on, we were able to achieve high-precision production management. To ensure that the leather maintains a stable and high level of quality in terms of luster, hand feel, three-dimensionality, color, smell, weight, etc., Double Helix spares no efforts in this regard.
