Magnetic Discs Grand 20 mm, black, pack of 10 (model mgk0080025)

Pack of 10 black magnetic discs by Grand, each disc 20 mm in diameter. These compact magnets are designed for holding papers, lightweight objects and small tools on metal surfaces such as whiteboards, refrigerator doors or filing cabinets. The low-profile, round shape and uniform finish make them suitable for visible display, temporary fastening and simple organisation tasks in offices, classrooms, homes and workshops.

Advantages

The 20 mm diameter provides a balance between compact size and holding capability, allowing neat placement without obscuring large areas of material. A black finish reduces visual distraction on dark surfaces and blends discreetly with many environments. Sold as a pack of 10, the set offers multiple attachment points for organising documents, reminders and small items. Reusable magnetic fastening eliminates the need for adhesive or drilling, preserving surfaces and enabling quick repositioning.

How to use

Place the magnetic disc directly onto a metal surface and position the paper or object between the magnet and the surface so the magnet holds it in place. For best results, ensure the metal surface is clean and free of dust or grease to maximise contact. Multiple discs can be used to secure larger sheets or to distribute holding force across an object. Remove by sliding the magnet off the edge of the item or by lifting it from the side to avoid abrupt separation.

Usage recommendations

Use the discs for lightweight items only; avoid relying on them to secure heavy or safety-critical objects. Store magnets away from electronic media, credit cards and devices sensitive to magnetic fields. When attaching to painted or delicate surfaces, check that the surface is suitable for magnetic contact to prevent scratches or marks.
