VEGETABLE-TANNED LEATHER Leather: Full Vegetable Tanning Leather Unused. From "hummel," a brand born in Denmark that has expanded widely not only in team sports like football and handball but also in the fashion field, comes the collaboration project "hummel PRAY with minority," which embraces diversity. The project emphasizes, "In a society where being different is often ridiculed, it's important to understand that it's okay to be different." Furthermore, as a quality-first MADE IN JAPAN model, it uses vegetable-tanned leather from "Tochigi Leather," one of Japan's top tanneries. Through tanning using tannins from Brazilian mimosa instead of chemicals, the leather is prone to sunburning, oxidation, and absorbing water and oil, requiring regular maintenance. However, this allows you to enjoy the color change to a beautiful amber over time and with maintenance. Yamato Takkyubin (Japanese courier service) shipping is free. I have various items for sale.
