These 3/8" Neodymium Cube Magnets are deceptively strong. While they are powerful and can pinch, their power can be quite useful. They are a great size for a bulletin board or your fridge, as just one of them will hold a stack of papers firmly in place, and they are large enough to grab and easily move. Strong and sturdy!

This size is also available in Grade N52 as part number B666-N52 and with a 3/32" hole through the center as part number B666-03.
