12 Pack Neodymium Bar Magnets Heavy Duty, Powerful Permanent Rare Earth Magnets with Double-Sided Adhesive, Super Strong Magnet Bar for Kitchen, Fridge, DIY, Craft, Garage - 40x10x5mm

The magnets are very strong. I used them to provide a better catch on 2 steel rural mail boxes. No tools or adhesive required.

Dimensionally accurate enough for my 3D printing. Strong magnets, a bit brittle but for the price its exactly the value that I expected. For a 10 cent magnet it's great!

High quality and very powerful magnets !!

I purchased these magnets to use with my new Blackstone 22 inch grill. As a table was not included with my new grill, I need a way to hold the various grill utensils to my separate metal table that I use with the grill. These magnets are strong enough to hold the utensils to the table, but they are so strong that it is hard to remove the utensils when you want to use them. The magnets will not easily release the utensils and therefore slide up the edge of the table when you try to remove the utensils off of the magnets. Other than that these magnets hold well, actually a little too well for my liking.

These are very strong magnets. They hold a lot of weight. They are very small; make sure you like the size. Since they hold a lot of weight, I am okay with their small size.They come in a nice little case. Slide them off of each other versus pulling them apart.

Nice. Good and strong just like I wanted. Decent price too. I'm happy. 😁

Strong but apparently made of glass. I had two snap together from an inch away and one shattered. Then, I accidentally dropped the bag with the rest (slid off my lap to the floor) and 3 more shattered in to an almost sand like substance. So, I have 2 left of the 6 and can't really use them without treating them like a newborn baby.

Started off using 8 of these magnets on the back of a commercial paper towel dispenser to stick to a fridge. Ended up using all 12 that I ordered. They work, I just expected I would only need to use a handful and have some extra for other projects.
