High Density Smoothfoam 3"Diam. x 3 7/8" H BELL -CASE OF 1000 pcs

3"Diam. x 3 7/8" H Smoothfoam Bulk Foam BELLS -CASE OF 310 PIECES - Our polystyrene bell shapes are a good alternative to Styrofoam ®. Smoothfoam is also know as EPS (expandable polystyrene) Smooth Styrofoam - Smoothfoam is made from EPS (expandable polystyrene). It can be manufactured in different densities. Our High Density Smoothfoam items are over 4 lb/ft3 density and our Low Density is 1.25 lb/ft3 How is that figured out? If you had a 1 cubic foot of our low density product it would weigh 1.25 lbs and the high density would weigh 4 lbs. High density Smoothfoam items are more durable (less dents and blemishes), and have a better, smoother finish because of the smaller beads. Low Density items are softer. So better for hot wire cutting, projects that require sticking items (pencils, skewers, etc) into it.
