You have to see it to believe it—this is arguably the most convenient item I've ever sold. It's an ultra-thin, ultra-lightweight 3X magnifier/bookmark that's truly unique. I guarantee you'll want more than one, so I'm selling these in sets of two. I've never seen anything quite like this. It's perfectly flat, yet it magnifies threefold. And if you put two of them together, the magnification doubles to 6X! It's paper thin—literally only 1/50 of an inch thick. It's flexible, bendable, and completely shatterproof. The magnifying glass is approximately 2.5" in diameter, and about 5.5" long, but it weighs about the same as a penny. I keep one in my phonebook, and another in whatever book(s) I'm currently reading. I keep one in my office, another in my bedroom, and a third in the kitchen. I have two in my glovebox. They fit easily into a pocket or purse, toolbox, glovebox, briefcase, toiletry kit, and of course any magazine or book. I know you'll like this product—it's truly exceptional.
