A big help for interior inspections in most hollow-body instruments! This versatile tool is a combination LED mini flashlight and handy swivel-jointed mirror attachment that adjusts in any direction. It telescopes waaaaay out, to let you illuminate and inspect areas deep inside large instruments where most mirrors can't reach. It's slim enough to fit into mandolin and uke soundholes, too—one tool does it all. The reliable lifetime LED light reflects off the mirror to shine where you need it. Easily detach the mirror to use the tool as a standalone flashlight. Convenient pocket clip included.
