Highly Porous Open Cell GOLD FOAM
Introduction
- GOLD FOAM is a lightweight metallic gold foam material designed for DIY craft projects, model making, event decoration and visual merchandising. The foam blocks feature an eye‑catching gold finish, are easy to cut, carve and glue, and can be shaped with a craft knife, hot wire cutter or basic hand tools. Ideal for creating 3D letters, display bases, signage, props and background elements with a premium gold look.
- Perfect for weddings, parties, retail window displays, stage sets and photo backdrops, GOLD FOAM offers a bright, reflective gold surface that stands out under natural or artificial light. The material is light yet stable, easy to paint or combine with glitter, vinyl, fabric and other decorative elements, helping designers, event planners and crafters quickly build custom gold‑themed decorations and professional‑looking displays.
Specifications
