I came across this video on YouTube and thought: Kaizen Foam??? Whether this product name is a misuse of the continuous improvement terminology, or a true productivity tool – I will leave that to you. YMMV. Still, it is worth a look.
According to the manufacturer, Kaizen Foam is designed to help you achieve maximum organization and visual control in your workspace. Kaizen Foam separates between the layers creating a perfect fit for all your tools in drawers and on walls. Sizes come in 2′ x 4′ sheets in thicknesses of .875″, 1.125″ and 2.250″. Black and White sandwiched foam has 1/8″ black layer on white foam for quicker visual indication of missing tools.
