Here we have our ever-popular 1/4" cubes in a black nickel finish. The black nickel plating gives the magnets a shiny, charcoal-colored finish. They are all the fun of the B444, just a different color.

This size is also available in grade N42 with our standard Nickel plating as part number B444, in grade N52 as part number B444-N52 and with a 1/16" hole through the center as part number B444-1.
