PRODUCT DESCRIPTION: GOGGLE NOT INCLUDED!  This fog wiper is a manual device that allows the user to slide a magnet/wiper on the outside of the lens, causing an inside magnet/wiper to move in unison and wipe off fog.  SIMPLE!  This product works even with prescription lens masks. Note that the unit price (quantity=1) is for one magnet/wiper on inside and one magnet/wiper on outside. If your mask has two separate lenses, you must order TWO units (quantity = 2).  Available in three colors: Black, Blue, and Yellow.

Wide-i fog wipers for Scuba Diving/Snorkel Masks, Swimming Goggles, Professional Dive Helmets, Airsoft/Paintball Masks, and Firefighter Masks are also available at eBay.
