Foam Blocks – 8x4x2 in.

The brick-shaped block that does a bit of everything.

Compact 8" × 4" × 2" blocks stack, glue and carve cleanly, so you can build up, cut down or wedge them right into place.

• What you get: 8" × 4" × 2" blocks in 9- or 18-packs.
• Made for: Floral arrangements and vase inserts, stacked sculptures and props, terrain hills and ruins, cake pop and candy displays, and classroom projects.
• 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.
