120 Pack Galaxy Slime Kit for Kids – Glow in the Dark DIY Luminous Slime (neon colours)

What it is and why people buy it

This 120 pack Galaxy slime kit is a bulk-style DIY party favour aimed at kids: you get multiple portions of glow-in-the-dark slime in six neon colours. The appeal is pretty straightforward—after a short “charge” under strong light, the slime is designed to look luminous in the dark. It’s the kind of sensory activity that works well when you need lots of small gifts for events, rather than one single showpiece.

On paper, it also leans into the idea of different colours representing different moods, which can be a fun hook for kids (and a decent classroom conversation starter). If you’re planning birthday goody bags, rewards, or a galaxy-themed party, this format is clearly built for that kind of use.

The essentials: colours, texture, and glow

The kit includes a total of 120 pieces of glow-in-the-dark slime across six neon colours: blue, orange, light blue, green, purple and yellow. The colour concept is tied to emotions—mischievous, happy, panic, sad, angry and excited—which is mainly a creative framing rather than something you can “measure”, but it can make distributing the slime feel more intentional.

Texture-wise, the slime is described as ultra-stretchy, soft and smooth. That matters because slime that’s too stiff can be frustrating for younger hands, while slime that stretches nicely is simply more satisfying to knead, pinch, squeeze and stretch.

For the glow effect, the instructions are simple: place the slime under strong light for a few minutes, then observe it in the dark. The stronger the light, the brighter it’s expected to glow—so if you’re buying for a dimmed party room or a dark corner of a classroom, that’s where it should perform best.

Key points to consider before you buy

A big part of the value here is quantity. With 120 items, it suits bulk gifting, classroom rewards and party bags. What it may not be best at is “long-term crafting” or deep DIY projects, because the activity is more about sensory play and light-to-dark effect than building something complex.

Also, glow-in-the-dark toys are often a bit dependent on conditions. You’ll get the brighter glow if the slime is given strong light first, and if you don’t, the effect may feel underwhelming. It’s not a deal-breaker, but it’s worth matching expectations to how it’s used.

Finally, the kit does call out storage needs: after play, return the slime to its container and seal it, and avoid prolonged exposure to air to prevent drying. If you’re using it in a busy setting where kids repeatedly open and leave it out, you may spend more time managing containers than you’d like.

What stands out in everyday use

If you’re imagining a party moment, this is the “quick wow” type of item. A simple micro-routine could look like this: charge the slime under a bright lamp or by a sunny window for a few minutes, then guide kids to a darker area so they can watch the glow. Because each colour is different, distributing small portions can feel more like a mini activity than just handing out sweets.

In classrooms, it can work as a reward that keeps hands busy while still being relatively low prep—again, as long as you have a practical way to seal and store portions between sessions.

Where it shines vs where you might want alternatives

It makes the most sense if you’re trying to achieve one of these goals: lots of small gifts, classroom rewards, party bag stuffers, or a themed event where the glow effect is the main attraction. The portable, compact approach is also positioned as a reason to include it in goody bags and gatherings.

If you’re after a single premium slime experience—something that’s more controlled, customisable, or designed for repeated “serious” crafting—this kind of multi-pack may feel more like a value-for-money bulk filler than a hands-on hobby product. It’s not necessarily “wrong”, but it’s a different kind of purchase.

Is it a good fit for you?

It’s a good fit if you need a large 120 pack of glow-in-the-dark slime portions for kids and you’ll use the strong-light charging step before dark-time play. It also makes sense if you can help with simple storage (sealing containers) so the slime doesn’t dry out.

It may not suit you if you’re expecting a complex DIY kit or something that doesn’t require light exposure to get the glow. You may also want to skip it if your setting won’t realistically allow for careful sealing and storage after use.

How to keep the slime fresh (quick practical tips)

The kit specifically advises sealing slime back in its container after play and avoiding prolonged exposure to air to prevent drying. In practice, that means portion control matters: fewer interruptions, quicker “charge and play”, then straight back into sealed storage.

For the glow, follow the guidance to use strong light for a few minutes. If you’re doing this for a classroom or party, try to plan the timing so kids aren’t waiting around in the dark before they see the effect.

Box-facts and safety note

The product description states it is made from safe, high-quality materials and that it has passed ASTM, CE and CPC certifications. If you’re buying for a school or a family setting, that’s a helpful baseline—though, as with any sensory toy, adult supervision is still the sensible approach for younger children.

Final verdict

Buying verdict If you’re planning a birthday, classroom activity, or themed party where you want 120 glow-in-the-dark slime favours that kids can stretch and knead immediately, this kit ticks a lot of boxes—quantity, colour variety, and a light-to-dark play routine.

It’s not the best choice if you want a long, complex DIY project or if you can’t manage storage between uses. Glow results depend on providing strong light, so the effect is only as good as the charging step. For the right occasion, though, it’s the sort of pack that usually gets pulled into play quickly and distributed easily.
