Surfboard materials. Basically in surfboard materials, the surfboard is a sandwich construction: you have a polyurethane blank and a polyester resin and fiberglass. So you have two layers of fiberglass which, fiberglass, here's a four-ounce fiberglass, and then you have your resin that is also it's laminated onto the core of the board. You'll have your fins which go into the boxes, and you have your leash plug which your leash will be into it. And also the other materials is also the wooden stringer that goes down the center of the board. The other materials that we are using these days are epoxy, epoxy resins, and an EPS Styrofoam blank. And that's materials.
