Set of 3 Lens Caps - 3.5 x 5 inch Our Lens Caps feature a quick-connect buckle and tether to keep them securely fastened to your camera, bag, or belt-loop. The exterior of the Lens Cap is made using waterproof Nylon Taslan material that keeps out unwanted rain, splashes, or dust and debris. The elastic opening provides a secure grip around the lens shade. The LC-35X5 fits lens shades with the approximate dimensions of 3.5-inches by 5-inches (3.5" x 5"). There is a bult-in White Balance Card that provides both structure to the Lens Cap and a convenient focal point for white-balancing. There is also a small interior pocket that can be used for carrying lens-cleaning tissue or as a convenient business card holder.
