When sourcing real fur, quality is determined by pelt density, hair length uniformity, and skin suppleness. High-grade fur should have a dense underwool and silky guard hairs. You must check the leather side (pelt); it should be soft, creamy-white, and free of cracks. Avoid pelts that feel 'papery' or stiff, as this indicates poor tanning processes. For specific types like Mink or Fox, ensure the color consistency across different panels of the garment to avoid 'patchy' appearances in bulk orders.
