Skin at a glance: Rare Tec-9 (am_ossify) from the Rain Forest collection. Multicolor electroplating: grey metal base with semi-transparent lime-green abstract pattern—calm, minimal, and a natural fit if you’re building around Rain Forest tones.

Should you buy?

Verdict: Buy if you want a source-clean, low-hype Tec-9 for a Rain Forest set or a quiet inventory—not if you’re chasing float flex or pattern lottery hype.

• Pros: Single collection line (no mystery case pool); wear cap 0.0–0.08 (Factory New & Minimal Wear only); pattern usually holds up well; look stays cohesive at a distance.
• Cons: Not a trending “meta” skin; only two wear tiers, so price gaps between FN and MW can feel sharp for what is essentially a niche finish.

Wear & float (read before you pay)

Allowed float: 0.00–0.08. There is no Field-Tested or below—if a listing looks beat up, double-check the float; something’s off.

| Tier | What to expect |
|------|----------------|
| Factory New | Sharpest lime transparency; coldest grey read on the metal. |
| Minimal Wear | Greens can read slightly more “lived-in”; transparency shift is often more noticeable than on louder skins—MW vs FN is worth comparing side by side. |

Shop tip: On C5GAME or the Steam Community Market, match float number + in-game screenshot. Narrow factory wear window means small float differences can matter to collectors even when the skin isn’t “float god” famous.

What to inspect in-game

Use Inspect in Game and rotate light:

1. Grip — where the abstract green breaks or fades; easiest place to spot wear eating into the underlayer.
2. Barrel — pattern continuity and brightness; good for comparing two listings.
3. Magazine side — pattern breakpoints show clearly here; use this when judging “same skin, different listing.”

Multicolor electroplate means green depth shifts with angle—don’t judge from one flat thumbnail.

Where it comes from (no shortcuts)

Dropped only via the Rain Forest collection—no standard case pool. Completing the set or hunting obscure Tec-9s? This one stays on the checklist.

Released 14 Aug 2013 with The Arms Deal—among the early tradable finishes. Old drops and keys from that era give it a small “vintage pocket” vibe for some buyers.

Expert muttering

Valve in-house, no Workshop credit—reads like an engine material / electroplate experiment, not a illustrated story skin. That’s why it ages well for people who hate busy art: from far away it’s one cool grey Tec-9; up close it’s mineral green under glass. I wouldn’t overpay for pattern index drama here; do overpay (a little) for float and clean sides if you’re finishing Rain Forest. If the listing title says “blue gem” energy, scroll past—wrong game. When in doubt, C5GAME float + your own inspect beats seller poetry every time.
