The thickness of each filter must not exceed 6.5 mm. The filter bag holds 8 round filters up to 95 mm (49 mm/52 mm/55 mm/58 mm/62 mm/67 mm/72 mm/77 mm/82 mm). The filter bag is made of EVA+ polyester fiber, which protects your filters from dust, vibration and splashes. The filters are contained in ten separate microfiber-lined pouches, which are easily accessible by opening the zipper. You can see all your filters at once and quickly put them in or take them out. Compact enough to fit in your camera bag.
