hello
I do not think that $ 50 you can get a genuine crocodile strap, and I'll explain why
a crocodile skin of good quality, at a cost that can range from 6 to 9 € x cm. width, the price varies by type of tanning
usually for the wide leather straps are used from 24 to 28 cm, the cost is easy to calculate and can range from 200 to more than 300 €
with a skin of this size, if you're a good cutter, and do not make a mistake you can get 6 / 8 straps.
add sewing everything by hand, finish the edges, making passers-by about three hours
try to make some accounts (if you do not have underpaid Chinese workers) with the risk of making mistakes and ruining a strap
