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\u003eCan I glue pieces together to build bigger?\u003c\/strong\u003e\u003cbr\u003eYes. 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.\u003c\/p\u003e","brand":"Silverlake Craft","offers":[{"title":"6 Pack","offer_id":44082094309576,"sku":"CFB4x12x2-6","price":24.99,"currency_code":"USD","in_stock":true},{"title":"12 Pack","offer_id":44082094276808,"sku":"CFB4x12x2-12","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/5906\/6824\/files\/d9fc5558-f880-5c20-8253-5422b5bec77b.jpg?v=1725489153","url":"https:\/\/silverlakecraft.com\/products\/foam-blocks-4x12x2-inch","provider":"Silverlake Craft","version":"1.0","type":"link"}
