Crystal Magnifier with Compass Rose

This is handy. A magnifier with the compass points etched into the base so you can line it up with the compass rose on your chart. It's a 4-power magnifier, is 3" in diameter, and almost 1-3/4" tall, and heavy enough to keep the chart in place. Scratch resistant crystal, this comes in a nice felt-lined box. From the fine folks at Weems and Plath.
