Review on Helix 300Mm Plastic Magnifying Magnification by Tom Duncan

What happened to those rulers? When we were kids you could find them everywhere. I'm just glad I found another one online because it's a lot more useful than a regular flat ruler without being too clumsy or awkward to use as a regular ruler when you don't need it to magnify something . When you do this, it takes half a second to move the ruler over the small text and another half second to return the ruler to use as a guide. I love this line and will keep them as long as they last because they seem to be rare these days.
