Micro-Mark CosFoam，EVA泡棉，白色，4mm厚，4張

The 4mm thickness is exactly right for my armor pieces—rigid enough to hold shape but still easy to cut with a utility knife. I was surprised how clean the edges came out on my first try.

I've been using these sheets for a cosplay helmet build, and the foam cuts cleanly without crumbling like some cheaper brands I've tried. The 4mm thickness gives just enough rigidity to hold its shape while still being flexible enough to curve around rounded parts.

I’ve been using these sheets to build a pauldron for my cosplay, and the 4mm EVA cuts so cleanly with just a hobby knife, no tearing or rough edges. The white surface takes a light coat of primer without issues, so painting has been straightforward. Definitely ordering more before my next convention
