Mr. Pen Architectural Scale Ruler, 12 Inch, White, Contractor's Scaling Ruler, Drawing & Drafting Tool

Prompt shipping. Very nice scale.

Having signed up for a scenery painting class, one of these was required to do scaled reproductions. I've never used one before but found the look of this to be high quality. My instinct was right. This heavy, aluminum ruler is easy to read, feels nice in the hand and stands up to a bit of wear. Highly recommended for practical use.

Really great tool to have. A little more affordable than in the office supply store.

This is a nice, sturdy scale. The only issues I noticed were: 1) The colored indicators for the three sides are a nice touch (you don't need a separate sliding indicator to remember which scale you're using), but they are just thin tape strips and can come off very easily. 2) The three corners on each end of the triangular scale are very sharp! I used a sander to bevel over the soft aluminum to make it less dangerous to work with.

Excellent solid aluminum quality product at a good price. As a bonus, could clearly be an effective self defense tool with the corners as sharp as a knife point. Clearly, NOT for children.

All of my scaled rulers were chipped up and warped, so I thought I'd splurge on an aluminum ruler. This little guy is pretty accurate and the aluminum and will resist chipping unlike the wood or plastic ones I already have. One of the nicer things that I've noticed about this is that the center groove on each side is color coded so I can work visually rather than picking it up and flipping it around for the proper scale. In this case, I work in 3/8" and 3/4" scale a lot, so I am always looking for the blue stripe. Perhaps this is common on newer scale measuring sticks, but it is new to me as an adept amateur, so it is really delightful in a kind of common way. I'm concerned that the printing on the ruler may wear fast, it is fine so far with only a couple months of use, but the marks are printed and stand proud of the surface, not engraved. This is going to fail and wear away at some point, but so far so good.

Love these rulers. They are solid with a good weight to work with. Great for drawing work and very sturdy.

Very helpful for scale measurement
