These round magnetic circles are made of strontium ferrite and flexible plastic and have a self-adhesive backing. You can use them to attach photos, cards, drawings, etc. to iron surfaces. Simply pop a magnetic disc out of the sheet, remove the adhesive film, then attach the dot to the backside of a card or something similar and press down firmly – and that’s it! Now you can hang the card on the fridge or a magnetic board.
If you order one piece, you will receive one sheet containing 24 magnetic circles with a diameter of 20 mm.
