## Description

Product Description

Review: These magnets have real pulling power! - We needed some magnets that definitely stuck to steel through a couple of layers of polythene insulation. The added problem was that there was only a narrow gap for us to put the magnets on. After careful use of two layers of aluminium tape for each of the 16 magnets in this pack, our problem was resolved. Unlike so many magnets we have used in the past which can be brittle if dropped, these are smooth on all sides, so don't look as if they will flake when coming sharply into contact with other magnetic items; I think they will be solid enough to last. They are a perfect size for what we need, and we will probably be ordering more, as they seem a bargain! (Basically, the insulated windscreen cover was not as snug a fit as we wanted, and it let in too much light. Careful placing of these around the edges quickly sorted it.) They are small enough so as not to get stuck on every steel item nearby, but still work extremely well.
Review: Very very strong - If you just want an average magnet, then don’t buy these. They are so strong you have a hell of a time trying to separate them as they come in two stacks not only are they stuck on top of another but the two stacks stick together side by side. The magnets I received are so strong I had to try and part them with a blade and when I did get them apart, if there close to any others they snap back together often nipping my fingers. These are very strong magnets and do what they say on the tin and then some.
