As follows:

1. Fully dyed horsehide. DoubleHelix's fully-dyed oil-waxed horsehide needs to be soaked in oil-wax during dyeing, so it cannot be dyed multiple times. Only S-grade raw leather can be used to produce oil-waxed horsehide with good color. The leather made has a thick feel and a strong three-dimensional feel. The leather surface is shiny but not ostentatious, and the longer it is used, the better the gloss will be.

2. Blue dyed horsehide. Dyeing leather with Indigo is a very difficult process. The blue-dyed horsehide made by this process will show the visual effect of aging tannin. Although the development cycle is long and the production cost is high, it provides players with a richer wearing experience.

3. Tea core horsehide. The so-called tea core is the brown effect produced on the leather surface after use. This is because the color of the leather core is different from that of the leather surface, and the color of the leather core is revealed.
