Foam Cubes – 5x5x5 in.

The in-between cube you'll keep reaching for.

Bigger than a 4", easier to handle than a 6". These 5" cubes hit the sweet spot for carving, stacking and decorating.

• What you get: 5" × 5" × 5" cubes in 4- or 6-packs.
• Made for: Sculpting and carving, centerpieces and floral bases, giant dice and photo props, display risers, and holiday décor.
• The material: White 1 lb density EPS (expanded polystyrene). Smooth, lightweight and rigid, and dense enough to take real weight.
• 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.

How much weight will it hold?
It's firm enough to take real weight and will dent before it breaks. For heavy or repeated use, add a hard coat like plaster, joint compound or a foam coating.
