Hi I'm Kristi with Stuller. I want to introduce to you today the Primo magnification glasses.  They come in a two, a two-and-a-half, a three, and a three-and-a-half magnification.  It does come in a kit. You're going to get a polishing cloth, a screwdriver, and a lanyard, along with your magnification optics mounted onto a set of safety glasses. They also are offered in a clip-on for those of you who have eye glasses.  The magnification on the glasses are going to vary depending on the optics. I have the two-and-a-half power on and the working distance is about eight to ten inches.
