Gui Gui Slime Kits Guide: Mini Slime Keychains & the Huntrix K-Pop Demon Hunters Collab

What makes Gui Gui different from other slime

Most impulse-buy slime is a one-and-done novelty. Gui Gui's kits are built to be customizable and reused — a 5-step process rather than a single pre-made blob — which is why it's held up as a repeat purchase for us instead of a single-visit item. The mini keychains take the same real-slime idea and shrink it down to something that clips onto a backpack or lanyard.

The core Gui Gui lineup

Surprise Slime Kits

The Gui Gui Surprise Slime Kit 2-Pack is a mystery bundle — two kits, each a surprise until opened, with gloss or clear slime and a small toy gift that varies. This is the flagship format the brand built its name on.

Mini Slime Keychains

The Gui Gui Mini Slime Jar Keychain is a pocket-sized jar of real slime with a clip attached — sold as a single, or in 2-, 3- and 5-packs for party favors, lunchbox surprises, or just spreading the cost across more kids at once.

The Huntrix collab: Gui Gui x K-Pop Demon Hunters

This is the line driving most of our Gui Gui traffic right now. Each kit corresponds to a character from the Huntrix crew in Netflix's KPop Demon Hunters — Rumi, Mira, Zoey, and the hard-to-find Derpy — reimagined as a slime kit. You've got two ways to shop it:

Mystery single pack — one randomly selected character, sealed, for anyone who likes the chase.

Guaranteed sets — the 3-pack gets you Rumi, Mira and Zoey with zero randomness, and the complete 4-character set adds Derpy so you own the entire collab without relying on luck. There's also a random 2-pack for a middle option: two kits, two mystery reveals, but a shot at landing Derpy along the way.

Which Gui Gui kit should you buy?

New to the brand and just want to try it? A single Mini Slime Keychain — low cost, and it shows you the quality of the slime itself before you commit further.

Huntrix fan who wants the chase? The mystery single pack or the random 2-pack.

Huntrix fan who wants the complete set, guaranteed? The 3-pack (Rumi, Mira, Zoey) or the full 4-pack if Derpy matters to them.

Party favors or stocking stuffers? The Mini Slime Keychain 3- or 5-packs — enough to go around without paying a per-unit premium.

Frequently asked questions

Is this real, usable slime?
Yes — Gui Gui kits are customizable and reusable, not a single-use novelty. That's the core difference from a lot of cheaper slime toys.

Is the Huntrix collab officially licensed?
Yes, it's an official Gui Gui x KPop Demon Hunters collaboration tied to the Netflix film.

What age are Gui Gui kits for?
Rated 6+ across the line.

Can I pick which Huntrix character I get?
Only in the guaranteed sets (3-pack and 4-pack). The single pack and the 2-pack are sealed mystery formats.

Who is Derpy?
Derpy is the hardest-to-find character in the Huntrix collab — included guaranteed in the 4-character complete set, or as a possible pull in the mystery formats.

Bottom line

If your kid just wants slime, the core Mini Keychains and Surprise Kits are the affordable entry point. If they're into KPop Demon Hunters, the Huntrix collab is the one to grab — mystery packs for the chase, guaranteed sets if you'd rather skip the gamble and just get the full crew.
