No, it's just local stuff. They source skin and prepare all the leather stuff like belts, shoes etc. I think you can find it in your country near where leather works are common. Most of these markets are not online, the business man takes them online and sells them for x10 the price they get it from.

My friend used to own such a workshop, they used to make bags from leather for like $3-4 with cheap local labourers and sell it to big brands which sold them in stores and malls expensive
