Updated at 17:01 UTCListed on 7 of 8 markets · 424 offersOffer counts show how many copies are for sale, not how many have sold. A market with only a few offers can have its price set by a single listing. Each row shows how far it sits above the cheapest price, and “price only” means the market shows a price without a link. The wear tiles and the table by wear also count Steam listings, so their offer counts run higher.

Cheapest price across all markets, by version.Float ranges are the standard wear bands, cut to this skin's own float range. The premium is how much more the StatTrak™ version costs than the regular one in the same wear. “Thin” means very few offers, so one listing can set the price. Offer counts here include Steam listings.
