Shagreen is a type of rawhide consisting of rough untanned skin, historically from a horse's or onager's back, or from shark or ray.
[1] Shagreen has an unusually rough and granular surface, and is sometimes used as a fancy leather for book bindings, pocketbooks and small cases, as well as its more utilitarian uses in the hilts and scabbards of swords and daggers, where slipperiness is a disadvantage.
In the 17th and early 18th centuries, the term "shagreen" began to be applied to leather made from sharkskin or the skin of a rayfish (probably the pearled ray, Hypolophus sephen).
The water-resistant qualities ascribed to the finish are probably why there are many toiletry cases and associated objects such as shaving kits, snuff boxes and other items of a personal nature.
There was a definite resurgence in items being made during the 1920s and 1930s, the lean hard finish and traditional pale green tone lending itself very well to the prevailing Art-deco style.
Small decorative items made of shagreen and silver have become popular in Southeast Asia; most are manufactured by high-end design studios in Thailand.
