[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 applied to smooth non-metal surfaces for secure storage of pens and other small items. [Compatible With 6-20MM Pens] Made from reusable, non-deformable silicone, the dual-direction elastic loop design ensures a stable fit for various pen sizes. Lightweight and designed to stay on the pen during use, it offers convenience and helps prevent loss. [How To Use It Correctly] For maximum magnetic strength, ensure the largest surface area of the pen holder is in contact with the metal surface or magnetic sheet. Do not use the side with holes for attachment. [Various Usage Scenarios] Suitable for use on any smooth surface and easily removable. Ideal for holding refrigerator notes, securing charging cables on desks, and organizing lightweight items such as keys, scissors, and other objects under 200g.
