Steel Core Polyball™:

Adding a magnetic stainless steel core to the already premium quality Polyball™ provides customers with a detectable screen cleaning ball that outlasts and outperforms the rest. Stainless steel cores are sized specifically to the outer dimensions of the Polyball™ to ensure detection by magnet or metal detector in any system. Americule’s solid stainless steel core is the ultimate solution.

Pigmented Polyball™:

Americule offers customers its traditional Polyball™ in a variety of colors, using only FDA-approved pigments for blue, red, green, yellow, purple and black balls. These colored Polyballs™ have the same premium qualities as the standard Polyball™ including abrasion resistance, durability, and rebound.
