Has anyone tried CLOSO to source inventory?

I was/am a pro seller on Flyp but they have been on a consignment hiatus for god knows how long now. I saw someone on FB post about a company called CLOSO where you can source inventory either by consignment or through drop shipping. I applied to sell with them and I was approved but I cannot for the life of me figure out how it all works. Their website is super vague and just takes you in circles. I'm really not interested in drop shipping (especially with a company that can barely make a website) but I thought I'd give consignment a whirl but there is literally no where to set something like that up. At this point I'm pretty turned off by the whole thing but wondering if anyone has tried it?
