The Kupo 17.5-inch Flex Arm Kit is built for making tabletop photography easy. Ideal for Dots and Fingers accessories, the flexible arm can also be used for taking photos from a frog-eye perspective. You can attach Dots having a diameter of 3 to 10 inches and Fingers with a length of 12 to 14 inches. The arm has a 3/8"-16 female thread at either end. You can attach the hex end to a Convi or Super clamp, and the other to a Dot and Finger holder. Turn the included M4 screw to lock down the adapter.
