A leather accessories brand founded by brothers Gen Takahashi and Dai Takahashi, designers. The word "irose" is an archaic word meaning brother. This is a word that is said to be the origin of the word "color." Made in Japan with high quality leather and attention to detail. The three-dimensional structure uses Japanese craftsmanship techniques, such as folding and assembling a single piece of leather without sewing, and carefully applying wrinkles to high-quality pigskin one by one by hand. The design is reminiscent of origami.
