result: 63/640 = 9.84% 48 stacks of 200 leathers = 9600 leather 9600 leather / 15 leather = 640 work gloves lol I have no idea if this was worth it but I think I am going to do another 640 work gloves when I find 640 more scrolls.
10m selling price per glove (assuming no depreciation) Cost: 30k per leather, and 200k per GFA 10% You get 50% profit
