It’s craft foam, not the blue insulation board. For clean cuts without loose beads, use a hot wire cutter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use it for fresh flowers?\u003c\/strong\u003e\u003cbr\u003eNo. EPS doesn't hold water, so it's made for silk, dried and artificial arrangements. For fresh flowers, use wet floral foam.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much weight will it hold?\u003c\/strong\u003e\u003cbr\u003eIt's firm enough to take real weight and will dent before it breaks.
