Magnetic Dots – Circular flexible rubber magnet pieces with a high-performance 3M acrylic adhesive backing. Peel off the release liner and stick to the back of paper cards, photos, lightweight crafts, or rigid substrates, then attach to any ferrous metal surface.
Typically supplied on sheets (e.g. 20 dots per sheet) and in bags (e.g. 5 sheets per pack), but sheet count, pack size, dot diameter, and thickness are fully customizable. Greater magnet thickness provides stronger magnetic attraction.
