curious to see how these hold up.Zombie bump, found this, will try one of the sets.
This is split up into 3 kits. One kit is 2 halves. Two 12x3mm Neodymium magnets per half - quite strong. Magnets are around 70mm / 2-3/4" apart. Halves snap together with magnets for easy storage (see photo).www.ebay.com
