Magnetic screw holder

When I disassemble something I need a lot of small boxes to store and separate the screws. I usually use cups or matchboxes but time to time I knock them off the desk. This issue brought this organiser to life. It has 19 small boxes to separate the screws. The bottom is magnetic, so you won't make complete mess.Requires overall 728mm 10x2mm magnetic stripe to be glued to the bottom, for the fixing.
