This Solar Sytem Kit comes with all the balls, sticks and rings. We even include an eyelet screw to hang it up when finished. This Kit is brand new. Other kits are made from extruded polystyrene (the rough, white porous foam plastic also found in craft stores). Extruded polystyrene is fragile and can limit your decorating possibilities. Dylite® on the other hand is a very diverse and durable product. It has a smooth finish so you can do detailed painting if you choose. There is also a huge number of coating materials availabe. Deco-art's acrylic paints and other coatings work very well. Any water based coating will work fantastic with our Dylite kit. Finished size is roughly 24" in diameter.
