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.

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.
