Self-adhesive products need to be placed, pressed and dried on suitable surfaces to adhere properly. Please read our FAQ about self-adhesive magnets.
The magnets will be delivered in pairs, meaning one half with a self-adhesive south pole and one half with a self-adhesive north pole.
A sales unit contains a strip with 5 magnet pairs, which equals 10 individual magnets. If you order 10 pieces in the shop, you'll receive a strip as show in the picture.
With 4 of these magnets you can, for instance, securely attach a light picture frame to a metal surface.
