This listing includes twelve sets of badge magnet attachments. Each set includes one magnet and one stainless steel back plate with 3M foam ahdesive. These name badge magnets are made of neodymium magnets glued on a plastic bar with metal insert. The easy peel-off tab on the adhesive liner makes the assembly much easier.
The dimensions of the magnet are 1 3/4L x 1/2W x 3/16"T ( 1.77" x 0.52" x 0.18").
In this design, there is a metal insert inside of the plastic bar so the product becomes very durable. This metal insert also forms a magnetic circuit with the two magnets and the back plate so the holding is greatly increased.
This is one of the most popular badge magnets.
