The new Dot Line Corp. Lens Cap Holder For Neck Strap is ingeniously designed to attach to the neck strap of the camera. The back of the holder opens, allowing the Cap Holder to be placed around the strap and snapped closed. Then, when the photographer takes the lens cap off of the lens, he has a ready place to put the cap...he just clips it to the holder and he knows where the cap is at all times. No more lost caps!. Designed to fit straps up to 2 inch wide.
