Grtard 100 Pack Ceramic Magnets for Crafts (small round disc magnets with adhesive backing)
Product description
What these magnets are for
These Grtard ceramic magnets are sold as a 100-pack for craft, DIY and classroom-style projects where you want lots of small discs without paying per magnet. They’re flat, round and described as having a ceramic build with features aimed at resisting demagnetisation and corrosion/oxidation over time.
On paper, the most practical angle here is the adhesive backing. If your project involves sticking magnets onto signs, labels, crafts, or small fixtures, the double-sided adhesive can save time compared with sourcing separate tape or glue. That said, the adhesive is only one part of the story: you still need a suitable surface finish and enough alignment/pressing time for it to hold properly.
A micro-example: imagine you’re making a classroom “sorting station” for different activity categories. You could stick the disc magnets behind small card holders using the included double-sided adhesive, then keep them attached to a metal board. It’s the kind of setup where having a big pack matters because you can afford a few trial placements.
Key features to notice before buying
This is a set of small round disc magnets with dimensions listed as 0.71 inch in diameter and 0.12 inch thick. Each magnet has beveled edges, which is the sort of small detail that can reduce the risk of scratching surfaces during handling.
Another detail that’s genuinely useful is polarity indication: the description states that the dots on each magnet represent the north pole. If your project depends on correct orientation (for example, arranging magnets to attract/repel in a controlled way), being able to distinguish poles quickly can prevent a lot of guesswork.
There’s also the promise of durability traits: the listing mentions demagnetisation resistance, plus corrosion resistance and oxidation resistance. If you’re planning to use them around showers, bathrooms or damp environments, those points are relevant—although you’ll still want to consider whether the adhesive and surface coating will cope with moisture in your specific setup.

What you’ll notice day to day
In everyday use, these are the sort of magnets that feel “small but plentiful”. A 100-pack is convenient when you’re running multiple small tasks—replacing one magnet that gets dropped, adjusting a craft design, or building sets for activities.
They’re described as having applications ranging from refrigerator magnets and shower doors to work/office use, scientific purposes, arts and crafts, and classroom activities. That coverage suggests the intended buyer is someone doing frequent small attachments rather than heavy-duty lifting.
Where they may fall short is if you need strong magnetic pull for heavier objects. The listing doesn’t provide pull force figures, and ceramic magnets generally aren’t chosen when you need maximum strength. So if your goal is to “hang” anything substantial, you’ll likely want to read more than just the pack size and adhesive wording.
Usage tips
Start by checking whether your surface is ready for sticking. The magnets come with double-sided adhesive in a matched amount, and the idea is that you can apply them when you need them. In practice, you’ll get better results if the surface is clean and not dusty/oily, and if you press the magnet firmly and evenly.
Also think about your final layout before committing. Because these are small discs, it’s easy to place them slightly off and then only notice when you try to align them against a board or metal panel.
Finally, remember the beveled edges can help with handling, but the magnet still needs careful positioning—especially in classroom or children’s craft contexts where small items get fiddled with.
Care & maintenance
The listing calls out corrosion and oxidation resistance, which is reassuring for normal craft use. Still, if you’re planning a damp or steamy environment (the listing mentions shower doors), the adhesive and the mounting surface become the weak link more often than the magnet body.
A sensible approach is to keep an eye on adhesion over time. If you see lifting edges, re-press the adhesive if possible or consider swapping to a mounting method designed for that environment.
Pros and cons to weigh up
What stands out - Bulk value: 100 magnets means you can test, remake and keep spares. - Each disc includes double-sided adhesive in the pack for easier mounting. - Beveled edges can help avoid scratching during handling. - North pole dots can make orientation simpler for DIY and classroom setups. - Listing claims demagnetisation resistance plus corrosion/oxidation resistance.
Worth noting / potential limitations - No magnetic pull-force details are provided, so strength may be more “craft useful” than “heavy-duty holding”. - Adhesive performance depends on your surface and environment, it may not be ideal for every wet or textured surface. - Small discs are great for craft, but they’re not designed for large-scale fixing jobs.
When it makes sense
It’s a solid pick if you’re doing arts and crafts, science-themed activities, classroom projects or office/work organisation where lots of small magnetic points are helpful. It also makes sense if you specifically want an adhesive-backed option and don’t want to source separate mounting tape.
It might not be the best choice if you need documented strength/pull force for holding heavier items, or if your project requires a mounting solution that will survive long-term in harsh conditions without relying on adhesive.
Final verdict
Should you buy it? If your aim is small-scale craft mounting and you like the convenience of double-sided adhesive plus a large 100-pack, these Grtard ceramic magnets look like a practical, value-for-money choice. They’re also well suited for projects where you need to distinguish north pole orientation.
However, you should be cautious if you’re expecting serious holding power or you’re relying on the adhesive for tricky environments—there aren’t any pull-force figures or adhesion specifics in the information provided. For “lift and secure” tasks, you may want to choose a magnet setup where strength is more clearly defined.
Mini FAQ
How do I know the north pole?
The listing states that each magnet has a dot representing the north pole, which can help you distinguish between poles.
Are these magnets adhesive-backed?
Yes. The pack includes double-sided adhesive alongside the magnets, intended for use when you need them.
What size are the magnets?
They’re listed as 0.71 inch in diameter and 0.12 inch thick (18mm x 3mm).
Are they suitable for damp areas like showers?
The listing mentions corrosion and oxidation resistance and includes shower door-style use in its examples, but adhesive and surface conditions still matter, so it may not be ideal for every bathroom environment.
What are they best used for?
Based on the listing, they’re aimed at crafts, DIY projects, classroom science and small office/work uses where you need many small magnets rather than maximum lifting strength.
