Silverlake Professional Craft Foam Boards - American-Made Hard Foam - 5-Pack 12x12x1.5 EPS Sheets for Dioramas, Models & Art Projects

Used this as a base for plants. It worked great and held up. It is true to size.

Its ok but you can easily fined styro laying around for cheaper

I found it essential to use a heat knife to carve this styrofoam without making a mess. At first, I tried using a (not-so-sharp) knife. That was a disaster. After cutting out my form with a heat knife, I smoothed the form somewhat with fine sandpaper. Rough sandpaper removes too much material. Acrylic paint worked well. Don't use E6000 glue to join pieces; it dissolves the styrofoam. Instead, use white craft glue.

NEXT DAY DELIVERYDidn't even have to find a store that had it, IT WAS DELIVERED TO ME!!Easy to carve and shape into final base for your modelA LOT easier to carve into what you wanted then trying to put thiner small pieces togother.

These thick 12” styrofoam squares were perfect for adding insulation when installing my bedroom window air conditioner.

I am satisfied with this product. I have not been able to utilize it but I know I will get a nice end product for my project. I recommend it. It is worth the money.

Expensive, but worked for what I ordered it for.

Fits the bill of what I wanted it for. Not as strong as packaging foam but if you just need it for crafting it's fine
