The device comes with 2 steel balls; a smaller and larger ball. The smaller ball makes finer lines in the sand, whereas the larger ball will of course make thicker lines. Similar to an Etch-a-Sketch, you simply shake the device to erase whatever drawing you’ve created. The sand will move around and settle in with everything flat and blank once again.
The Sandscript package includes 1 sand drawing machine, 1 package of sand, 2 stainless steel balls, and an AC power adapter. The magnetic sand drawing machine is designed and sold exclusively , measures 11.5 inches in diameter, and weighs 2.5 lbs.
