This Heavy Duty Magnetic Stash Container will stick to any magnetic metal surface and will require quite some force to remove it. We've tested it, and it will pick up metal objects weighing 20 kg+ with ease. It is loaded with 3 extra-strong magnets in a line, with a sizeable stash compartment that screws off at both ends.
The stowaway stash is made with a solid metal casing and two solid screw lids, so it will keep any contents extremely safe.
The storage compartment is 7cm in diameter x 13cm long.
A worthwhile investment for many static scenarios or transportation.
