How do you sell empty set to market? I was try it but it says 'Sorry, but you cant sell empty set'

buy a new empty set then put it on the market
Or just put a cheap item inside the set and sell it in the market

well apparently you can't sell a empty set. as above just put a cheap item in it.

If i cant sell it to market, how about this?

I think those are glitched ones OR they took the items out of the set while it is in the market
