Wow, this thing is impossible to sell at the current price. It's priced very close to a key so most people try to get that out of it. Even below current price it's unsuccessful. There's 6 pages on these on Outpost but most sellers want a key, which they clearly aren't getting. I also ignored all painted ones as well. Also worth noting in a trade with lots of items, this one always sits last.
