The StarFlash® Signal Mirror is a lightweight, virtually unbreakable signal mirror with a precision aiming system, using a targeting star with a retro-reflective fabric. The StarFlash Micro measures only 2" x 1.5" , is only half the size of the normal 2" x 3" signal mirror and easily fits in small tin type survival kits as well as other small containers. Both sizes have a lanyard hole for convenient attachment to gear. The Micro weighs only 0.5 oz. (14g) and the 2"x3" weighs 1 oz. (28g). It should be noted that the StarFlash® is NOT a floating mirror.
