For the shaving kit, the campground or the kids, nothing says no nasty glass shards like plexiglass. This unframed, unbreakable, back-surfaced mirror is 3-1/2" x 2-1/2" x 3/32" thick. Please note that there is a protective film covering the front of the mirror which you need to peel off before using.

Couldn't tell it from the glass variety by just looking. This plastic mirror with squared off corners measures 3-15/16" x 5-15/16". Comes with protective film on both sides. We're thinking camping, lockers, deserted island or just a nearly-unbreakable travel item. Pretty flexible, too, if you like fun-house mirror effects.
