[Strong Magnetic Pen Holders] Our pen holder is made of silicone and features built-in strong magnets, allowing it to be directly attached to metal surfaces such as refrigerators. Magnetic sheets (12 included) can be used on smooth non-metal surfaces for secure mounting of pens and other small items.
