Camera ID tags helps you to easily identificate cameras on set! Just put it on viewfinder, matte box or body and keep your cameras tidy! The most important thing is that they are reusable! Forget about making tape lebels on each set! Come in a set of three: 1 big (50x50mm) and 2 small (30x30mm) fits most of the viewfinders and matte boxes. Come with hook velcro on one side. We also add a loop velcro strip to the package to install on the camera.
