Foam Blocks – 8x12x2 in.

A solid foundation for your next build.

Wide, flat and a full 2" thick, these 8" × 12" blocks hold pins, stems and sticks firmly and give dioramas a base that won't flex.

• What you get: 8" × 12" × 2" blocks in 3- or 6-packs.
• Made for: Diorama and terrain bases, cake pop and dessert displays, centerpiece foundations, carved signs, and model railroad scenery.
• The material: White 1 lb density EPS (expanded polystyrene). Smooth, lightweight and rigid.
• Shape & finish: Cuts clean with a hot wire cutter. Use water-based paints and glues; oil- and solvent-based products (including most spray paints) melt EPS.

Larger packs are ideal for classrooms, events and big builds.

Quick answers

Are these styrofoam blocks?
They’re what most people mean when they search for styrofoam: white EPS (expanded polystyrene), a lightweight foam made of tiny fused beads. It’s craft foam, not the blue insulation board. For clean cuts without loose beads, use a hot wire cutter.

Can I use it for fresh flowers?
No. EPS doesn't hold water, so it's made for silk, dried and artificial arrangements. For fresh flowers, use wet floral foam.

Can I glue pieces together to build bigger?
Yes. White (PVA) glue, foam-safe craft glue or a low-temp glue gun all bond EPS well. Avoid high-temp glue guns and solvent-based adhesives, which melt it.
