Zeus x27 | Tosai

Origin Story

The Zeus x27 | Tosai, released on April 1, 2025, as part of the Spring Forward update, features a custom paint job depicting a young koi fish. This design is directly referenced in its in-game description, which notes it "has been custom painted with a young koi fish, also called a tosai." The skin's flavor text, "Wishing you good fortune," further emphasizes the cultural significance often associated with koi. It is part of The Fever Collection.

Drop Chance

Zeus x27 | Tosai is Restricted, a Purple-tier skin in the upper half of the rarity ladder. From the Fever Case: approximately 3.20% per opening (roughly 1 in 31). The 15.98% Restricted tier rate is split across 5 Restricted skins in the case. StatTrak versions drop at ~0.32% from the Fever Case (about 1 in 313). These per-skin odds assume equal weighting within tier — Valve publishes tier rates but doesn't formally confirm even distribution across skins in a tier.

Skin Condition

Float range 0 to 0.7. Exteriors: Factory New, Minimal Wear, Field-Tested, Well-Worn, Battle-Scarred. StatTrak is available in FN, MW, FT, WW, BS.

• Factory New ($2.03): The custom painted young koi fish artwork is crisp and fully intact, with maximum color vibrancy and no visible scratches.
• Minimal Wear ($0.87): Very minor edge wear may appear on high-contact corners while the central koi motif remains nearly identical to Factory New.
• Field-Tested ($0.62): Noticeable wear on edges and some flat surfaces is expected, with small chips potentially intersecting parts of the koi artwork.
• Well-Worn ($0.55): More extensive chipping and scuffing are present, with portions of the koi fish showing visible interruptions where the base material may peek through.
• Battle-Scarred ($0.59): Heavy wear covers the weapon, with significant chipping, scratches, and fading that can obscure large parts of the painted koi elements.

Sticker Compatibility

The Zeus x27 | Tosai, featuring a custom-painted young koi fish, pairs well with stickers in red, orange, white, black, or blue, as these colors commonly appear in koi motifs. Stickers with Asian, luck, or festival themes also conceptually align with the skin's "Wishing you good fortune" flavor text. The forward body area of the Zeus x27 generally offers good sticker visibility.
