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" 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.

These little front-surface mirrors measure 22mm dia (that's a hair bigger than a nickel) x 1.5mm thick (which is pretty much the same as a nickel) and might have some grease pencil marks on the front side. But an old pro like you? You'll look right past those marks. Made in the USA.

You get a half-dozen of these 2-1/2" dia x 3/32" thick back-surface mirror glass discs. Call it the crafter pack. What you do with them is a reflection on you, or perhaps a reflection of you. Made in the USA.
