NEODRYS with its new inner core traps moisture quickly, helping to provide a superior dry field. No messy leaks, even with the core fully saturated. Its moisture-proof backing protects the cheek from abrasion and bounces light into the working area. With the new COMFORT EDGE, there is no stiff abrasive material to cause discomfort. Absorption, protection and comfort make NEODRYS far superior to any other product on the market. NEODRYS is available in two sizes large (blue) and small (yellow). PLUS a choice of two kinds of backing; white and new reflective.
