DHAP Orange sensor cleaning swabs (Vswabs) 1.0x / 24 mm - 12 per pack Swab comes from its unique letter "V" shape: The narrower edge of the V shaped swab minimizes the contact between the the swab and the chamber wall. This ultimately eliminates the lint produced inside the camera eventually from falling on the sensor Better maneuverability and easy swabbing while inside the chamber. Due to its triangular form The Vswab (patent pending) applies equal pressure to the edge of the swab pad. This brings a more homogeneous swabbing motion and less streaking along the edges
