SECIVLOT 4 Pack Pre-cut Polyethylene Pick and Pluck Foam, 16 x 12 x 2 Inch, Black, Foam Sheet for Cases

Works great for wall insulation and very easy to cut

worked great for what we wanted

The foam was exactly what I needed. The delivery was fast and on time. The foam is perforated making it easy to shape.

They were just what I was looking for. The foam is perforated in a ~1/2 inch grid. Once started, they tear apart reasonably well and it's intentional. They are just firm enough as well. They are about half way between firm and soft.

Great for making custom miniature cases.
