This sure is a foam sheet. I needed a foam sheet for reasons, and I bought this one, and it was indeed a foam sheet.
Came in a timely manner, no marks or scuffs, uniformly textured and colored.
10/10 foam sheet buying experience.

EVA Foam Sheets

I got 3 sheets of 3/8" black eva foam just to try it out for my armoured Batman suit. I had bought previously from another supplier but I'm really glad I switched. The sheets are just a tiny bit smaller but the quality is top notch! The density is good and it cuts and glues nicely. I have a new supplier now!

Thanks for a great product. I got a lot of foam for the price, and it’s great for my cosplay.

I did not purchase this for cosplay purposes but to use as a supplemental sleeping pad for backpacking. So far, works great.
