These are pretty funky looking and although the actual magnet part is tiny, they are pretty strong. Each magnet will easily hold a photo, or piece of paper in place on your fridge or other metallic object, and are strong enough to resist the door being slammed shut. The shape enables them to be easily removed, so good for those lacking manual dexterity. Not quite strong enough to hold several sheets of paper securely, but good enough for normal use.
I bought these as a present for my mum and they stick very well and have the strength to hold more than three things too. With regards to delivery, It was very quick to be dispatched and arrived equally as quickly!
