Mr. Pen- Machinist Ruler, 3 Pack, 6 Inch, Stainless Steel Metric & Imperial, Precision Measuring Tool, 1/64, 1/32 Graduation for Engineering, Carpentry, Drafting, Office, School

These rulers are perfect for my needs. I am measuring the placement of text blocks on a printed page, and the 10ths and 100the marks are clear and easily readable. I can't speak to the 'accuracy' of the marks, but I'm not doing machining, so they are plenty accurate for my needs. If you are a machinist, you'll probably want to invest in a good micrometer or caliper (guess-o-meter), but if your accuracy needs don't rise to that level, these rulers are very nice. The 12 inch length of the ruler is perfect for my needs since I am measuring items on a 8.5x11" page. The metal thickness is acceptable, and the marks are engraved and colored black, so I don't think they'll wear off any time soon. Overall, these rulers are a good value, and I would order them again!

Perfect for multiple applications. The zero edge, multiple sizes of rulers and clear & precise markings make these so useful. The sturdiness and weight of these imply that they are high quality, long lasting and super functional.

When shopping for office items, I go out of the way to find and buy items by Mr. Pen and these are my 6th purchase from them. My experience over the years has always been excellent when choosing/using Mr. Pen items. They manufacture products of the highest quality and then provide the best Customer Service, even with lower priced items. These machinest rulers are of the quality I expected clearly etched and thick, unflexing steel. I will continue to buy Mr. Pen when given the opportunity. In fact, I'm here to make purchases #7 & #8 of Mr. Pen!

just what I wanted easy to read well made good price

Everything I’ve bought from Mr. Pen has turned out to be of exceptionally high quality, and these splendid little rulers are no exception. They’re precision tools. Inches and centimeters are shown in tiny fractions, clearly and durably printed on the edges. My only small complaint is that the edges are a little sharp in the hand, and should have been more smoothly polished.

Note that the largest ruler does come with a sleeve just like the others; I just lost it. These four rulers are nice, made from stainless steel. The edges are sharp enough to slice you, which is good for accurately tracing lines. They come in two lengths and two widths. All measurements are in millimeters: The first is 355.50 long, 26.25±0.05 wide, 0.91±0.02 thick. The second is 304.50 long, 26.20±0.05 wide, 0.91±0.01 thick. The third is 203.00 long, 19.37±0.01 wide, 0.90±0.01 thick. The fourth is 152.00 long, 19.16±0.01 wide 0.90±0.01 thick. All measurements are approximate. All of them appear to be almost perfectly flat (which is impressive), and straight on the business edge. The markings are thin enough that you don't lose accuracy, and it is easy to precisely measure up to 500 microns. Even further, I found it easy to eyeball accurately down to 100 microns because the lines are so thin, straight and sharp. I also like the font. One issue you may note is that the ends are a cut a little bit rough. They have a slight bevel where a guillotine severed the length. Additionally, they do not appear to be perfectly perpendicular with the longest edges, and have a slight variance. This variance means that if you're trying to measure from the zero-end, your measurements will be off slightly. I have a picture attached with the markings lined up which illustrates this issue. It is more noticeable from the imperial side on the 300mm long ruler, which means that particular ruler has a slight offset on that specific side. As for the orange and transparent sleeves that they come with, I have a complaint. These are almost not worth keeping, but only almost. You can't hang them by a nail through the hole because the cut is on the wrong end (gravity), and this makes me wonder why the hole is there in the first place. The tops are also heat-sealed, which means that you can't remedy the problem by sealing the bottom and opening the top. I understand that these sleeves are almost definitively just for protecting the markings and brush texture during transit, and they are still useful for this purpose. Nevertheless, the material is thin and the design cuts prevent them from being more useful. It would have also been nice if cardboard outer-sleeve were more durable, as I would like to keep them in this. There is no easy way to open the package without ripping this packaging. All in all, great rulers for the price. Regardless of my complaints, this is still a 5/5 star item.

Nicely machined and marked rulers. Very handy for the craftsman. It's good to have a three pack because they are easy to misplace. Good product and good price.

One of the best rules, scales, machinest ruler. What ever you call it, it is AMAZING. I dont know who designed this but they deserve an award. Its functionality is amazing. It doesn't slip and the bendability is just right. Not to flimsy but rigid. There is no assembly required. Just a great all out ruler. Has both inches and metric

Perfect set of rulers. They have every measurement i could possibly need.

Si se ven bien. El acabado de los bordes un poco filoso. No tanto como para cortarse los dedos (creo).

Cheap but well cut and accurate - ideal for the price - i would recommend these.

Finally, exactly what I wanted! No maddening 1/10” scale, no metric so you can measure off both edges of the ruler and the scale starts right from the ruler end…no indentation. Also, one side 32nds and 64ths all marked out, while the other side is the standard 1/8” and 1/16” markings. As well, the ruler is a nice width with almost no flex to it, nice and stiff. The only thing not perfect is that it comes with a storage sleeve that has a hole punched at the top for hanging, but the pocket is open at the bottom so the ruler just falls out when you hang it. Easily fixed though. Buy them!!

These rulers are excellent quality with well made marking that should last a long time. I checked some of the measurements against a very accurate caliber and they are spot on. The ends are exactly 1 unit from the first appearing mark, thus it is accurate to use for measuring with the end flat against something.
