Yes — it's a genuine, NetEase-backed marketplace and the largest in the world by volume. Trustpilot sentiment is middling (2.6/5), but the core marketplace itself is legitimate and widely used as a pricing benchmark.

Can I use BUFF163 outside China?

Not really. Deposits and withdrawals require a verified Chinese identity and phone number, so non-Chinese users cannot fund an account or cash out, even though the site itself is browsable.

Why do other sites reference 'Buff price'?

Because BUFF163's massive trading volume makes its prices the most reliable reference point in the CS2 skin market — many other marketplaces and pricing tools quote it as a benchmark even when their own users can't trade on BUFF163 directly.

PROS

The world's largest CS2 skin marketplace by trading volume, with millions of active listings covering CS2, Dota 2, and TF2
Backed by NetEase Inc., one of China's largest technology companies — real corporate weight behind the platform
Pure peer-to-peer model: skins trade directly between buyers and sellers rather than passing through the site's own inventory
A 2.5% selling fee is among the lowest of any major skin marketplace
So widely used that its prices are treated as a reference benchmark across the wider skin-trading ecosystem, even by sites you can actually use internationally

CONS

Non-Chinese users cannot deposit or withdraw funds at all — this is the single biggest issue for most readers of this list, since it makes the marketplace effectively unusable for international trading despite its size
Full KYC requires a verified Chinese identity and phone number, which by design excludes almost everyone outside China
Trustpilot sits at a mediocre 2.6/5 from around 95 reviews
The interface and support are primarily built around a Chinese user base, so navigating disputes as a foreign user is impractical even where technically possible

Review

BUFF163 (buff.163.com) is the largest CS2 skin marketplace in the world by trading volume, operated by NetEase Inc. since 2018. It runs as a pure peer-to-peer marketplace — skins move directly between buyers and sellers rather than sitting in the platform's own custody — covering CS2, Dota 2, and TF2, with millions of active listings at any given time.

The scale shows in the numbers: a 2.5% selling fee undercuts most competitors, and BUFF163's prices are so widely referenced that other marketplaces and pricing tools across the entire skin-trading ecosystem quote 'Buff price' as a benchmark, whether or not their own users can actually trade on BUFF163 itself.

That last point matters because most readers of this list can't actually use it: BUFF163 requires a verified Chinese identity and phone number for KYC, and non-Chinese users cannot deposit or withdraw funds on the platform at all. It's a real, legitimate, NetEase-backed marketplace — Trustpilot sits at a middling 2.6 out of 5 from a small sample — but it's built for the Chinese domestic market first, with the rest of the world along for the ride only as price-watchers.

If you're outside China, treat BUFF163 as a pricing reference rather than a marketplace you can actually use — check its listings to understand fair market value for a skin, then trade on a platform that actually accepts your region's payment methods and identity verification.

About highlighted.gg

What is highlighted.gg?

highlighted.gg is an independent review platform for CS2 gambling sites: case opening, case battles, skin upgraders, crash, roulette and skin marketplaces. Every review is researched against public sources and scored with the same published rubric — games and design, bonuses, payments and support — so ratings are comparable across sites.

We explain exactly how we rate on our methodology page, and our editorial policy covers how affiliate links and promo codes are handled. When a site gives us no way to verify ownership or licensing, the review says so.

How we review sites like BUFF163

Our BUFF163 review follows the same checklist as every CS2 case opening site we cover: what games it runs, whether its provably fair system can actually be verified, how deposits and skin withdrawals behave, what the bonus terms really say, and whether the operator publishes ownership and licensing information.

Sub-scores on this page feed the overall rating, and the promo code was last verified on 2026-08-13. If something changes — codes, bonuses, ownership — the review gets updated, not re-dated.

How to check if a CS2 gambling site is provably fair

“Provably fair” only means something if you can re-compute the roll yourself. A legit CS2 gambling site publishes a server seed hash before you bet, lets you set your own client seed, and reveals the server seed after rotation so every case opening, battle or upgrade can be re-derived.

You can verify any supported site's rolls in your browser with our free provably fair verifier — no signup, everything runs locally. Our blog walks through the math with worked examples.

CS2 gambling promo codes and bonuses

Most CS2 case opening sites offer a signup bonus — free balance, free cases or a deposit boost — activated with a promo code. Codes change and bonus terms carry wagering requirements, so we re-verify the codes in our reviews and date-stamp them.

The current BUFF163 code is on this page, and every active code we track is collected on our promo codes hub with the terms decoded.
