I don't really need this item and I was considering selling it. However, I couldn't find any in shops or in trades. Would anyone be able to help me price this?

10-20m is reasonable, but with Morostide coming up more might pop up on the market.

Thank you very much for the advice! I'll hold off until Morostide, then, just to see.

I'd put it on sale for, say, 20m now and see if anyone is interested ;) More items on the market = lower price. If there's no interest, you can always lower the price.

Aaaah yeah, that's true. I've tried putting it for sale before (at a higher price), but nobody nibbled at that line. I'll try advertising it!
