Have a public inventory?
Import your steam inventory and see which skins you own
The easiest way is to open your steam profile in a web browser,
and paste your steam profile into the ID Box above.
Otherwise, you can use your steamID64 Link, or Steam URL Alias Name
Do not enter the username you enter to log into steam (never give that to anyone)
After completing an import, all the decorated skins you own will show up green on this site!
You must have a public Backpack to be able to import your inventory (And own the skins on this site)
