looking for a certain material, been used to line toolboxes

[Schugg]

im not talking about the stuff your mom puts in the kitchen cupboards with the small foam balls and holes. i have no clue what this stuff is, its can come 1/2" thick, black, plastic/foam mix, its flexible and you can cut it without it falling apart. i know its not made for lining tool boxes but ive seen alot of people use it for that. i believe snap on has it, but the stuff in the magazine isnt very discriptive, no names and its expensive. so that didnt help me to be able to find it somewhere else. the shop im at has it in their toolboxes because its the military and they are obcessed as hell about sh1t being perfect and organized. i know this will sound dumb, cause back before i joined i would have said thats stupid as hell, but they used it to cut the shapes out of every wrench, socket, plier, extension, and any other tool in the toolbox drawers, layed the sheets in the drawers and the tools in their cutout spots. its mainly for tool accountability cause thats a big deal to them too, but its helps alot with finding what you want ALOT faster. and it seems they have rubbed off on me. and i remember how long it would take me to find a 12mm socket in my dads toolbox full of sockets just bouncing around everywhere, so i figured im going to do the same thing. sure i could get the little socket/wrench holders that lay down in it, but thats not good enough being im pretty picky.......if anyone has any clue what this stuff is let me know! i asked the people in the shop but none of them knew

ok well i finally bought the material form sears, tried using a styro cutter thing for the cutting but it sucks and i ended up breaking it trying to make it better. then my wife found things versa-tool thing from walmart which is probably the best thing you can get to do this. its pretty much just a soldering iron with alot of other tips, one tip happens to be a exacto knife so it works nice. did my first set of wrenches and it looks pretty decent.
