This ultra thin multi fiber fabric has a patented folding design to create a softer edge compared to a hot sealing process, yet designed to be compatible with a wide range of our solutions (VDust Formula, Sensor Clean, Smear Away).The patented mini-channel, with contour, provides an even saturation of the paddles surface while preventing pooling and vertical flow at the edge. This reduces streaks associated with traditional flat surface paddles. The mini-channels also provide the extra reservoir to absorb the excessive liquid and prolonging the moisture life of the swab during the cleaning process. For use with Visible Dust 1.3x sensor size range (20mm). 12 per pack
