Magnet discs NOBO 38 mm, black, pack of 4

NOBO magnetic discs, 38 mm diameter in a black finish, come as a pack of four flat-topped magnets designed for secure attachment to whiteboards, notice boards and other ferromagnetic surfaces. The compact round shape provides a discreet hold for papers, photos and light documents while remaining easy to position and remove without scratching or leaving residue on most surfaces. These magnets are suitable for office desks, classrooms, meeting rooms and domestic organisation tasks where a reliable, minimalist fastener is required.

Advantages

The flat-topped design provides stable contact with magnetic boards and easels, reducing the chance of slips or curling at the document edge. At 38 mm diameter the discs strike a balance between holding power and compact form, making them suitable for small to medium-sized sheets and prints. The black finish offers a neutral, professional look that blends with typical board frames and interiors, while the pack of four supplies multiple attachment points for charts, notices or photo displays.

Suitable for

• Fixing notes, memos and to-do lists on whiteboards and notice boards
• Attaching diagrams, photos and teaching materials in classrooms
• Holding light documents and printouts in offices and meeting rooms
• Organising schedules, reminders and small displays at home

Key specifications

• Pack quantity: 4 magnets

How to use

Place the magnetic disc on the outside of the paper or photo and bring the assembly into contact with the magnetic board; the flat top provides a stable hold. For larger documents, use two or more magnets spaced evenly along the edges to prevent curling. Remove by lifting the edge of the disc and sliding it away from the surface—do not pull directly on the attached paper to avoid tearing. Store unused discs in a dry place away from sensitive electronic devices and credit cards.

Usage recommendations

For optimal holding strength, clean the magnetic surface before use to remove dust or debris. Use multiple magnets for heavier or larger sheets, and avoid placing magnets near pacemakers or sensitive electronics. Replace magnets that show wear or chips to maintain secure attachment and prevent scratching of display surfaces.
