Mongolian Lamb, Explained: Fur, Shearling and Faux
“Fluffy” covers a lot of materials. They are not the same thing.
"Fluffy" covers a lot of materials. They are not the same thing.
Here is the plain version.
Mongolian lamb is lambskin with long, curly wool still attached. The wool grew on that skin. Because of that it is fur, not fabric. It is also sold as Tibetan lamb. The long, loose curl is its signature.
Shearling is sheepskin too, but the wool is cut short and even. It is denser and flatter. It is the material of coat linings and the cuffs of winter boots.
Faux fur is synthetic fibre, usually acrylic or polyester, knitted or woven into a fabric backing. It is animal-free. Its curl is set into the fibre and can mat or frizz with wear.
How to tell real from faux, on any bag. Part the fur with two fingers and look at the base. Real fur grows out of skin, which looks like soft leather. Faux fur sits on a woven or knitted backing, often with a visible grid of threads. Then look at the tips. Real hairs taper to a point. Synthetic fibres usually end blunt.
The Brown Fluff bag is real Mongolian lamb, in a deep chocolate brown. It is not faux and it is not vegan. Every jelli.world jelly bag, by contrast, is TPU or PVC, with no animal materials at all.
Each material has its own care. Real lamb wants to be shaken out after use so the curls lift. It wants a barely damp cloth for marks, fingers rather than a brush, and dry weather. Radiators dry out the skin. Faux fur copes better with a damp day but can melt near high heat.
One rule: know what you are buying, then care for it accordingly.
Brown is the most forgiving colour for real lamb. It hides a day's wear and goes with every autumn coat.
