Instead of messy powders and pastes, molds and glues, you can create your own tunnel and landscape designs using natural , volcanic pumice.
Pumice has a natural look and feel, is lightweight, and easily carved.
Great for first timers or veteran modelers. Use the pumice for ballast, cargo, land cover, almost any size landscape, model rock walls and fences, and tunnel needs. Pumice can be carved, colored, sealed, and glued.
