Closed Cell Sponge Foam Sheet Roll, 1/2" T x 17" W x 80" L, Perfect Cosplay Padding, DIY Project Sheet - Easy Cut Non-Adhesive Multi-Function Soundproof Foam

Using the foam to line a case that houses a paintball marker. The foam is softer and less dense than expected, but protects the contents of the case well enough to protect the marker from damage during transit. Too much pressure from a hard edge dig snag the foam and rip a bit. I did not end up using the adhesive backing and cannot comment on its strength. Using a dull utility knife did result in jagged edges of course, and the thickness of the foam requires multiple layers. I may use the remainder of the foam to line a tool drawer, but will find a different foam for the travel case due to the wear and tear.

Falls apart from menial use.

Good dense material, a little difficult to cut but overcome with a hot knife. Perfect thickness and makes a really good outline in the toolbox.

Overall I'm pretty happy with this roll of foam. I didn't have any problems flattening the sheet out and getting it unrolled after receiving it. Cutting it with a crafting knife and even a box cutter was super easy to do. I think it really depends what you'll be using this foam for. I wanted to try it for cosplay but the foam isn't dense enough in my opinion to hold intricate designs. Scoring the outside is no issues but it just compresses too much. If you're using this as pure padding or something to customize holding tools in a case though you'll be fine. Again its usefulness", is really based on your usage.
