It belongs to The Breakout Collection and can be unboxed from the Spectrum Case. The Ultraviolet finish is particularly sought-after for its distinctive appearance, and supply is inherently limited while demand remains high from collectors and players.

Float values in CS2 determine a skin's wear level on a scale from 0.00 (perfect) to 1.00 (maximum wear). With a float range of 0.06 to 0.80, this skin has specific wear availability that affects pricing. Lower float values within any condition category (e.g., 0.01 vs 0.06 in Factory New) result in cleaner appearances and typically command higher prices. For high-value trades, always verify the exact float value using inspection tools.

Prices for the ★ Butterfly Knife | Ultraviolet vary across marketplaces due to fees, regional pricing, and seller competition. This skin can be obtained by opening the Spectrum Case or purchased directly from third-party marketplaces.
