Midwest Cellfoam 5mm, 11 1/2"x11/ 1/2" ~ 5921

Lighter than Balsa and tougher than other foam sheets, Cellfoam is an extruded closed-cell Polystyrene used in craft, architectural, diorama, scenery and foamie model applications.
Cellfoam has a consistent, smooth, flat surface without paper liners for flexibility.
It accepts most paints, including water-based, enamels and latex and most adhesives, including Epoxy, foam-safe CA, water-based and polyurethane, and can be cut with ordinary hobby and craft tools. Cellfoam's cell structure allows sanding.
