MP5-SD | Phosphor is a Classified SMG skin from The Danger Zone Collection, which entered the CS2 economy alongside the Danger Zone Case in November 2018.

The float range for this finish is restricted to 0.00–0.80, so Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred are the only obtainable conditions on the open market. The restricted range is set by Valve at the time of release.

A StatTrak™ version is available, which tracks confirmed kills made while the skin is equipped and typically commands a premium over the standard finish. Active listings for MP5-SD | Phosphor are tracked across 18 marketplaces, with prices spanning $4.14 to $57.16 depending on wear, variant, and seller.
