Well-made magnets

antennafinJanuary 13, 2026

I've used 7/8" magnets in my craft for years, but evidently those aren't available anymore. These are smaller at only 18 mm, probably not quite as powerful as 7/8, but strong enough for most of my uses. I adhere magnets to my crafts using E-6000 adhesive so I was happy when I received them without the glue pads already applied. I was afraid I was going to need to scrape a glue pad off of each magnet. They are well made, better than expected, but I wish there was a dimple or paint spot to indicate polarity like the other magnet sizes I use. Read more

Great little magnets!

Crystal OlivaresNovember 2, 2025

I used these to attach some under-cabinet lights and they worked great. The adhesive backing is strong and installation was super easy — just peel, stick, and press. The magnets hold securely but still make it easy to remove the lights when needed. Definitely recommend for small projects like this! Read more

★★★★☆

Not as strong as Neobendium, but cheap and hand to have around the shop.

Eric ChristensenDecember 14, 2025

A nice selection of different-sized adhesive-backed magnets for general use. These are not as strong as Neobendium magnets, but plenty strong for many applications. The adhesive is solid VHB tape, which sticks well to properly prepared surfaces. I keep a box or two of them on hand in my small parts cabinet and am amazed at how often I find applications for them. Great value for the price. I have often paid more than this for just a couple of magnets at the local hardware store. Now I have them in stock and don't have to stop working on a project to go fetch magnets. Read more

Worked great on cruise cabin doors

MsDebWJanuary 5, 2026

I used 3 magnets to hold a wooden star shaped signs on cruise cabin doors. They worked great however they slipped a little on doors that slammed shut. The wooden stars were light weight but maybe I needed to use 4 magnets each. Read more

Super strong magnets

WyattEDecember 27, 2025

These are a small round heavy duty magnet! They were great, super strong and very small to make it convenient. It was a great buy for the money. They are fun to use on a lot of different things and they are not breakable. You can get a lot of use out of these magnets. Read more

★★★☆☆

Not exactly as described

Melanie A. BassettJanuary 11, 2026

Not as strong as described and there is NO adhesive backing. I guess you get what you pay for. Would not order again. Read more

They work well

Chris RoseJanuary 3, 2026

I put them in my sockets and they hold the bolts really well they’re at the right size where they’re not oversized but they’re really strong. They work really well. Read more

Great product!

Monica DanielleJanuary 3, 2026

I’m a teacher, and I used these on the back of letter and number cut outs. I made them into magnets so that I could easily change out the date on my whiteboard each morning. They are super easy to use, adhesive is strong, and I love that there are different sizes (although that hasn’t made much of a difference for what I have used them for). Read more
