MIRUM® delivers the appearance of premium coated leather with a natural, non-plasticky hand feel and no noticeable odour.

Due to its thickness and stiffness, it is not recommended for garments or designs requiring significant drape, heavy pleating, or high seam tension.

Durability:ISO durability testing is not currently available. However, MIRUM® has demonstrated strong durability in commercial use and has been successfully adopted by multiple brands, supported by consistently positive long-term user feedback.
