Foam Cubes – 4x4x4 in.

Crisp cubes, ready to become anything.

Clean-edged 4" cubes that are easy to carve, paint and stack. Small enough for a single project, plentiful enough for a whole classroom.

• What you get: 4" × 4" × 4" cubes in 6- or 12-packs.
• Made for: Giant dice and photo props, floral arrangements in small pots, cake pop stands, carving and sculpting practice, and kids' craft days.
• 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 cubes?
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.
