In the secondhand industry, products are typically categorized into Grade A (Cream), Grade B, and Grade C. For Japan bags, Grade A/Cream refers to items with no visible wear, no stains, and functional zippers, often including high-end brands like Coach, Michael Kors, or luxury labels. Grade B may show slight signs of use but remains highly salable. You should prioritize suppliers who provide a detailed sorting list and ensure the bale contains a balanced mix of leather and canvas materials to maximize your retail margin.
