## Description

Mr. Pen- Machinist Ruler, 3 Pack, Metric, Precision, Stainless Steel, 6 inch - desertcart.com

Review: Good rulers for 10ths and 100ths visual measurement - 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!
Review: Quality and Highly Functional - 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.

### ⭐⭐⭐⭐⭐ Nice thin markings, easy to be precise
*by J***T on December 7, 2023*

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.
