FloraCraft SmoothFōM Block 1 Inch x 5.8 Inch x 11.8 Inch White

This was just the flimsy foam that you find inside a packaging box. It fell to pieces when I used a sharp utility knife.

Buyer beware: I bought this FloraCraft Smooth Styrofoam Sheet 1"X6"X12" for a craft project. One side is smooth and the other side crazy wavy. Quality styrofoam should be smooth on both sides. This is definitely NOT what I expected for almost $5.00!
