I've been wanting to price suggest this item forever which is why I've been very picky with accepting any items offered as I generally wanted pure, however:

I'm not exactly sure how this will work in terms of getting it priced, but I recall the price being cut off to what the buyorder were on the item which is why I put the suggestion at 1000 keys. I assume the most likely possibility is waiting for recent Clean Sparkle Luger sales before this suggestion is accepted due to the price on those being 10 months old, however I also know that sometimes there are certain exceptions with collector item trades as both items are incredibly rare collector items in general.
