Sumind 3 Sets Tool Box Shadow Foam Organizers Tool Box Liner Adjustable Inserts Foam Non Slip Liner Mat for Tool Box, Cabinet and Chest Drawers, Black Top and Red Bottom (10.7 x 18 Inch)

Strong double sided tape. Just bear in mind the red material is harder to cut than the black material. All good.

This is a great tool foam for a DIY. Ive tried other types of foams and theyre so hard to cut by hand. This one I was able to do a whole sheet in less than half hour. I didnt do a great job but Im happy as long as the tools stay in place. If you take your time you can get perfect custs. The other good thing is you can peel layers of 3 thickness levels before you hit the bottom black layer which gives you the desired depth.
