## Description

TRYMAG Small Flexible Magnets Round Disc 18x3mm for Crafts with Adhesive Backing, 20Pcs Tiny Flat Circle Ferrite Industrial Magnets for Office, Classroom, Science, Hobbies, Project - 0.7Inch: desertcart.com: Industrial & Scientific

Review: Well-made magnets - 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.
Review: Great little magnets! - 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!

### ⭐⭐⭐⭐⭐ Well-made magnets

### ⭐⭐⭐⭐ Not as strong as Neobendium, but cheap and hand to have around the shop.
*by E***N on December 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.
