Foam Cubes – 6x6x6 in. (4 Pack)

Chunky cubes with room to carve.

Four hefty 6" cubes give you real material to sculpt, shape and build with, and they stay feather-light no matter how big the project gets.

• What you get: 4 cubes, 6" × 6" × 6".
• Made for: Sculpture and carving, oversized dice and party décor, centerpieces and floral bases, display pedestals, and costume props.
• 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.

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.
