Also meine 3D Badges sind definitiv nicht magnetisch

Ok, dann scheinen die Infos auf der Herstellerhomepage fehlerhaft zu sein...

Da steht das nämlich wie folgt:

DOME BADGES
Dome badges are printed on high quality 3" magnetic backed vinyl, with a high gloss weatherproof coating. Your first badge should be purchased with a mounting kit. Additional badges can be purchased separately.

3D BADGES

3D badges are laser cut acrylic designs layered for a unique visual effect with a 3" magnetic back. Your first badge should be purchased with a mounting kit. Additional badges can be purchased separately.
