Back with much better proof.

I was the only seller that has unpainted, uncraftable jingle belts until I sold them for:

I bought 2 belts for 1.33 ref and 1 for 1.44 ref:

As you can see, I owned 4 but I can't find the trade where I bought the 4th belt.

Found it on outpost. Check the item's history.
