This product is an excellent value for the amount of square footage offered, as compared to other retailer's liners I priced. I cut nearly 20 rectangular measurements for various portable metal toolbox drawers I wanted lined, with usable leftover. The 3mm thickness offers cushioning to heavier tools and I do not foresee ever replacing it. No buyer's remorse. All tools remain in-place, even small 3/8" & 1/4" sockets, and do not move freely when the drawers are slid as they otherwise would on bare metal, however a car ride will understandably jostle the drawers contents. As an automotive DIYer, I'm VERY pleased with the material, but one cautionary recommendation, some may prefer to buy a rubber liner for a toolbox that undergoes daily abuse (automotive repair shop) as years of grim and grease would be easier to clean off of firm, rubber liners. Again, NO REGRETS, try this product, I'm sure you'll agree it's well worth your while! I would purchase again.
