Teeny Tiny Cat suggested me to price this item at 5 refined using sales, but I have zero experience with that, I'll try anyway

2 sales at 5 refined

(Jupiter Jetpack not registered)

Both sellers got 5 refined from at least a single trade, but only one of them had the item registered in the history

Any criticism or extra proof is welcome
