Magnetica Original Buildable Magnets (2.5mm) 512 Set for Sculpture Stress Relief Intelligence Development and Desk Toy for Adults | The World's Best Magnets!

Waste of money. No wonder there are twice as many as most others. They’re 1/4 the size at best. If your on an iPhone X or Xs, they will easily fit inside a small letter o on the keyboard. Drop one and you’ll never find it. Very weak magnetic power even when combined together. Wish I hadn’t tossed the packaging or these would be going back for sure.

Have had these less than 3 months. Loved them initially but now they are starting to tarnish, leaving my hands black after I mess with them. Replacing now with another brand. Here’s hoping for higher quality next time.

LOVE THESE! The perfect thing to play with at my desk at work. Would 10/10 recommend! My roommate told me I was crazy for getting these... then played with them for 20 min!

My 13 year old son absolutely loves these magnets, and truth be told, I've spent quite some time playing with them as well. It is very satisfying to build various shapes and three dimensional forms, so is crushing them into a small ball only to start over. My only caution to anyone looking at these magnets is to make sure that you know what the size 2.5 mm really means. These beads are small, but if you know what to expect when you order, you will be very happy with your purchase.

Cons:1) Super small, the whole thing is the size of a penny2) The cube is very unstable. I don't think you can build it.Pros:1) turns out there are many cool shapes. Tubes, and more. Takes some experimenting to find stable configurations. Works like carbon! I really like it now!

My son is super bummed. He worked diligently on his chores to earn the money for his magnets. He couldn’t wait for them to arrive. Sadly, the joy quickly vanished as he discovered just how small the beads are. They’re half the size of the magnet beads that all of his friends have been bringing to school. I tried to convince him that maybe it’ll be cooler to have a miniature size, but he’s not having it...and now they’re gathering dust on my kitchen counter. Please be aware, these are not the same size as the popular magnet beads!

These magnets make a great fidget toy. I keep them in the office as a way to keep my hands busy. Occasionally, I wipe them with a Lysol wipe to remove any build up of oils. They are smaller than I originally expected. Something to be aware of, especially if you have young kids. (Pen for size reference)

I took these on a long car ride and they were so fun to create new shapes. We made a game out of it and had so much fun! The magnets are pretty small so the opportunities for creating things is endless. I really like the metal plate you can use to build with.
