There was probably a time when these were hanging on a wall in a craft shop in a land that wasn’t filled with big box stores. I was much younger then and was considered quite fair if not the fairest of them all! Note the package says “mirror studs” ha ha!! There are 12 in that package and some nifty pronged rings if you’re not using them Shishi style and there are 15 circles in the flex-o-mirror package.
So, in review we have studly mirror and flexo mirror. Reflect on the possibilities.
