As seen on The Big Bang Theory! Nanodots are kick-ass, take-no-prisoners, juiced-up super magnets. With no flashing lights and no batteries, these tactile dots derive their allure from magnetic force and human ingenuity. Nanodots are powerful magnetic constructors milled from Neodymium, the world’s strongest permanent magnet. Each dot is electroplated for durability and precisely crafted for the formation of magnetic structures.
