These 75mm diameter badges feature a powerful magnet in their backs, allowing the badges to attach to magnetic surfaces (most commonly fridges). The 75mm Badge has a generous display area, remains light yet inexpensive to produce. It has a display area up to 70-75mm in diameter.
A 75mm badge consists of a clear plastic disk (over your artwork), pressed on to a metal top cover, which locks onto a metal back with a compact magnet to attach the badge on to (magnetic) metallic surfaces.
Each Pack makes 100 75mm badges and contains:
100 x Clear Plastic Mylar Disks
100 x Top Covers (metal)
100 x Magnet Backs

This badge (showing a job number) is very commonly used to attach to vehicles awaiting service or repair in garages or service centres.

All you need to complete a 75mm badge is your own artwork (and an Alond 75mm Badge Machine).
