Nume Leather

A natural leather that gets better as it ages

Nume leather is produced through vegetable tanning. This tanning process faithfully preserves the original texture and even the pores on the cowhide, making Nume leather the most natural leather material. It has a sturdy grain, and its durability means it can be used for 10 to 20 years. The color of the leather deepens with use and the appearance becomes more lustrous, while the feel will become softer. Nume leather also exudes the rich aroma of leather. It's no wonder that the Nume series is one of Tsuchiya Kaban's most popular collections.

The Look of Natural Leather

We have chosen to keep natural markings such as scars, wrinkles, veins, and pores on the cowhide to showcase the natural appearance of the leather in our products. This is one of the most distinctive features of our bags. The appearance of the leather will vary depending on the part of the hide and individual differences between animals. Through careful observation, you will uncover your leather product's unique, one-of-a-kind appearance.
