The small size (110mm long) can hold postcards and sticky notes, the medium size (220mm long) can hold the short edge of A4 paper, and the large size (300mm long) can hold the long edge of A4 paper or the short edge of A3 paper. It can be attached to metal surfaces such as whiteboards, refrigerator doors, and cabinets. (Note: Cannot be attached to glass whiteboards, aluminum alloys, or other materials.) [Secure Adhesion] Built-in N35 powerful magnet, one magnetic bar can hold approximately 7-10 sheets of A4 paper. The adhesive force is stronger than that of a regular round magnet. [Easy to remove] The end of the magnetic bar is designed in an inverted triangle, which is ergonomic and makes it easy to remove. It feels nice and smooth to the touch. [Secures paper edges] The long magnetic bar can firmly secure paper and its edges, preventing paper from getting caught (embedded block magnet). Effectively avoiding the drawbacks of traditional round magnets.

This classic, solid-color set features a simple style. It's suitable for a variety of locations, including homes, schools, offices, and warehouses.
