Shape Retention EVA Foam

Shape Retention EVA Foam is a high-density craft foam sheet made for building, shaping, cutting, and detailing custom projects. Originally designed for cosplay armor and prop building, this EVA foam is also useful in the workshop for patterns, mockups, padding, templates, dimensional parts, sample builds, and creative fabrication work.

This foam has a smooth closed-cell structure on both sides and a high-density feel, making it easier to cut, sand, dremel, heat, and shape for cleaner results. The material is designed to hold shape after heat forming, which makes it useful for curved parts, structured panels, costume pieces, armor builds, and prototype work.

Shop Use

Use this foam for quick mockups, template building, pattern testing, cosplay pieces, structured details, and prototype work. The 3mm thickness is thin enough for detail work and layering, while still giving more body than paper or thin craft sheets.

For best results, cut with a sharp blade, heat form carefully, and test glue or paint on a scrap piece before using it on the final project.
