4 Pack Pick and Pluck Pre-cut Polyurethane Foam,16 x 12 x 2 Inch Pick Apart Insert Gun Case Foam Sheet for Tool Game Box Cases

It’s foam and they work. No flaking and the pre-cuts work for what I need in a storage box. I’ll buy more soon.

These things are awesome to use in mobile tool boxes. They are easy to cut and thick to fit and stack tools.

This is great. If you need to put this in a box to secure items. For us we needed it for a crown box. I wish that it had dividers in it so that you wouldn't be having to take out all the small sections or leave them but not totally secured together. We ended up happening to glue a couple of them together to keep them in place. I do love how easy it is to take out sections so you can custom make whatever size holder you need. This is a good buy and enough to do a couple of boxes. In the box

Used this foam on my toolbox to organize my hand tools and drill bits because I got tired of my bits getting mixed together with my other tools. The foam cuts easily if you are not using the precut pull out cubes. The pull out cubes work for most applications, but for pop some of my drill bits, I took a knife and made a slit to just fit it in between the foam slit. The pluck out foam is also on both sides of the foam. Good product overall for the price. You get four pieces

Made a big difference

This foam is advertised as polyethylene foam. It is not. It is polyurethane foam. The barcode/tag on the received item even says polyurethane. Big difference.

works as expected, quality product

I chose this to convert some simple, stackable boxes to an affordable miniature storage solution for Warhammer models. Overall, for that purpose, it's gonna work just fine. Each sheet is about two inches thick. Each 'pluckable' square is about a half an inch square. Foam is medium density and feels good. It isn't as easy to pick out each square as some other foams I've used and with such large squares you might have some negative space when plucking a space to accommodate smaller things, like models, but I don't foresee that being an issue. The name of the game here is value. As I mentioned in reviews of similar products - picking this up and tossing it in a box of your choosing will save you HEAPS over a pre-made foam storage solution. Just a bit more work. That's worth it to me, your mileage may vary.
