I have to buy it in a store not online.


I want maybe polyethylene or polyurethane.


Here's what I have in mind if my description wasn't coherent:

look in the phone book. Why not on line? I run a maintenance shop and we have all our tool boxes foam inlaid with red/ blue 2 part foam made to shadow tools. Plenty of places to buy it unless you live in a 1/2 horse town
