i wait bigger magnet balls like the image. anyway it's cheap

Friendly advice: the 5mm size is 10 times cooler... going back I would not buy again the 3mm. Also, the quality of the coloring is not so good. Literally I had no options because the 5mm are out of stock everywhere but really my advice is to wait for the 5mm and buy those.

Great toy for adults. Colors are very bright and magnets are very strong. Because of size (3mm), I would not recommend for young children as they could ingest and pose serious problems.

Okay, so not really surprising, but the 3mm refers to the cube, not the ball size. These magnets are miniscule. I can't imagine how children of 14+ are supposed to play with them.

Super product 👍 children love it and it is very constructive for intuitive and intellectual development. Good experiences simple and effective

Nice magnetic balls, arrived soon and as described. On later thought maybe I should have bought single color (all of them are nice) because with mixcolor it's harder to build somthing big and nice, since the colors get mixed. Anyway, nice product and nice magnetic power relatively to the size.

In the photo it looks a lot but when you buy it is quite small and it is quite difficult to assemble anything but it is quite cool and relaxing

Very good.. it's arrived in very good condition Everything is fine

Delivered in perfect shape. Spheres are too small, next time I'll buy the 5mm. Really good seller

way to awesome but it would be nice if they were bigger
