  • Really good magnets for the price!
Size: 15x2mm_50P
These magnets are great! I bought these for a board game I am creating and needed something to connect the pieces all together. The dimensions and tolerances on each piece are spectacular and these things are unbelievably strong! The only downside that I have noticed is honestly how strong they are relative to their size. The magnetic field of these are so strong that if you're not careful, when they snap together they will split in half or chip off small pieces. So, with that in mind, if you are looking for a strong magnet, this is the way to go! ... show more
