Evergreen styrene products are easy to cut with a hobby knife or razor saw and can be painted with enamel or acrylic paints. I have had excellent results using Testors plastic model cement to bond styrene. It's important to note that ODD numbered sizes of round tubing telescope into the next ODD numbered size (evg427 will fit into evg429). The wall thickness of this styrene tubing is .027 (0,69mm)
