Grtard 20-Pack Neodymium Magnets (60 x 10 x 3 mm) with Double-Sided Adhesive Strips

What these magnets are for

Grtard’s 20-pack neodymium bar magnets are the sort of “small, but don’t underestimate it” magnetic strips people reach for when they want a firm hold on DIY and craft projects. They come with double-sided adhesive film sheets that you can attach to one side of each magnet, so you’re not limited to using them only on magnetic surfaces.

On paper, the big draw is the strength and the practical backing: triple plating (Ni+Cu+Ni) is positioned as both a shine/finish and protection against rust. The set format (20 pieces) also matters if you’re building something that needs multiple attachment points rather than one or two.

Key features in everyday terms

The magnets are 60 x 10 x 3 mm neodymium bars. Each magnet uses adhesive film leaves (the listing mentions 4 adhesive film sheets per magnet), which you can stick on one side and then press the magnet to a non-magnetic surface.

That combination is useful when you’re trying to: - mount lightweight items to non-metal materials (like wood, plastic, metal, or ceramic, as stated) - create removable organisers for DIY setups - handle crafts where you need consistent positioning

One practical detail to remember: the bar itself is described as “very fragile”, so the way you handle them (and how close they are to other metal objects) will affect how long they stay in good shape.

What you’ll notice day to day (and what to watch)

These magnets are clearly intended for strong holding power. The listing goes as far as warning to keep them away from items that could be affected by strong magnets or where they could cause trouble.

They’re not just “strong magnets”, they’re positioned as powerful enough that you should treat them like powerful neodymium bars:

• Keep well away from your eyes and from electronics such as TVs, computer monitors, and phones.
• Keep them away from sensitive items like pacemakers and credit cards to avoid risk.
• Don’t let them collide with other metal objects, including another magnet (the listing explicitly says you cannot let them hit metal objects, including another magnet).

So yes, they can be brilliant for quick, solid attachment. But if you’re expecting a carefree, toy-like experience, that’s where things can fall short—these are strong, and that strength comes with handling rules.

Where they make sense (and who they’re for)

A set like this makes sense if you’re doing multi-use DIY, crafts, or small mounting jobs and you want a straightforward way to attach to both magnetic and non-magnetic surfaces.

It’s also a good fit if you’re thinking in “repeatable units”: for example, you might plan a small layout with several magnets placed around the same area, each one acting as a consistent anchoring point. The adhesive strips are designed to help with that—so you’re not limited to finding a magnetic backing.

If you mainly need one or two attachments, though, you may find yourself with extra magnets you don’t really use. And if your project involves frequent repositioning, you’ll want to consider how permanent the adhesive film feels once applied.

Tech specs (from the listing)

• Name: Grtard 20 Pack Neodymium Magnets with Double-sided Adhesive
• Type: Neodymium bar magnets

• Pack size: 20 magnets
• Coating: triple plated Ni+Cu+Ni (anti-rust protection is claimed)

Final verdict: Should you buy it?

Is it worth it?

Grtard’s 20-pack is worth considering if you want strong neodymium magnets that can also be used on non-magnetic surfaces thanks to the included double-sided adhesive strips. For DIY and craft use where you need multiple points of hold, the multi-pack format and adhesive approach are practical.

It’s not the best choice if you need something low-risk and easy to handle. The listing is very direct about keeping them away from sensitive items (including pacemakers and credit cards) and about avoiding collisions with metal objects, including other magnets. It’s also not ideal if your plan relies on magnets being handled casually.

If you’re set on buying, it’s smart to double-check how your surface type will work with adhesive (the listing mentions wood, plastic, metal, and ceramic) and to plan your placement carefully before pressing the adhesive down.

Quick FAQ

How do the magnets attach to non-magnetic surfaces?

You apply the double-sided adhesive film to one side of each magnet, then stick the magnet onto the non-magnetic surface (the listing mentions wood, plastic, metal, and ceramic as suitable substrates).

Are these magnets safe around electronics and credit cards?

The listing advises keeping them away from TVs, computer monitors, phones, pacemakers, and credit cards to avoid risk and interference.

Can I let the magnets touch other magnets or metal objects?

No. The listing specifically says it’s prohibited to let the bar magnets collide with other metal objects, including another magnet.

Are they designed to resist rust?

The triple plating (Ni+Cu+Ni) is described as providing protection against rust, along with a brighter finish.
