eBoot 2 Pieces Plastic Color Ruler Straight Ruler Math Rulers (6 Inches, Black)

I use various kinds of rulers every day for my work so I've got a very wide assortment to cover a big range of tasks. I needed a couple 6" light weights for two of my travel kits. They'll only get occasional use, so toughness/durability is a minor issue. I needed metric and inch scales, good accuracy, a little bit of flexibility, and a total length of less than 6.25" to fit in my fountain pen/ink pen/mechanical pencil case. (These measure about 6.1875") These rulers fit the bill perfectly. Marks are easy to read. Overall design is refreshingly minimal (not even a logo). The only improvement I'd suggest is to have a bevel on the inch side (as there is on the metric edge). The pair of black ones are perfect for my use, but if you might need some for your kids or other regular use where they may get lost or broken, consider the great deal on the four-pack of the clear ones from eBoot -- four for $6. Yes! eBoot rulers are highly recommended!

Great little straightedge. Perfect for everyday use.

Very easy to see the white on black. Nice edge. Good product.

You basically get what you pay for. They're inexpensive but incredibly flimsy. One of the two was delivered already broken straight out of the package.

Great for optical lenses

Very fragile. Broke in my shirt pocket while leaning over.
