NANODOTS 64 BLACK

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. Each Nanodot is 5mm in diameter, and the Silver and Gold editions are coated with authentic Sterling Silver or Real Gold. Available in 64-count or 125-count tubes.
