Add to your set one block at a time! Just choose your color!
*PLEASE NOTE: Due to magnet polarity, block colors must alternate. Blue blocks do not stick to blue blocks nor gray blocks with gray blocks. Fore example, when ordering individual blocks, rather than ordering 6 of a single color you will want to order 3 blue and 3 light-gray blocks, or 3 charcoal and 3 light-gray.
