6-Inch Plastic Straight Ruler Set, 15-CM Flexible Dual-Scale Measuring Tool for Student School Office, 1 Black & 1 Transparent

Like most rulers, the 0 is not on the edge, but these rulers are good and solid. I bought 10 sets for my STEM lab.

Simple item but very nice. I wanted a smaller ruler to keep in my sketch books (one for ink sketching and one for watercolor sketching). This pair was just what I was looking for. Just the right amount of sturdy, easy to read the digits and lines, and small enough to fit in the pocket of a sketch book.

Came with a clear and black ruler . Both just as described. 100% accurate. I ordered for nursing school and its worth is because it fits in a lab coat pocket. Definitely a bang for your buck and easy to use.

Just what I needed

Excellent

The white printing on black is really a pleasure. These usually come on a clear background (in a package with a white piece of paper behind them so you can't tell how "invisible" they are until you're home and have opened the package. Toss the clear one or use it for a spare; the black one is worth twice the price.

Second time ordering. This order the clear ruler was fine but the black one is missing printing on it. A pain that I need to return this to get one that is not defective.

This small ruler is exactly what I need. Well made 6" ruler. Recommend
