These provide an extra layer of security for your slabs, protecting them from damage in the event of an accidental drop, or during transportation.
The fit is great. Perfectly snug with no room to rattle about.
The case is metal and the viewing display is UV protected acrylic plastic.
There's a protective film on both sides.
Installation tip. Place the slab inside one half, then close the magnetic case from the side with the two nibs first (see photo #8) ensuring they're tucked on the inside of the other half.
