PAIR Black Acrylic Segment Rings Captive Bead Body Jewelry PAIR Black Acrylic Segment Rings Captive Bead Fast Shipping - Select your size from the above menu Material: Acrylic PLEASE NOTE - For the 8g, 6g and 4g sizes the segment is very easy to remove/replace by hand. The 2g was more difficult but still not too hard for me. I found the 0g and 00g much more difficult to remove/reinsert the segment. You may need something to assist you (tool to help spread the ring a little, and maybe a friend) while doing removing/reinserting the segment for the larger sizes. Ordering a quantity of one gets you a pair
