If you hang using the hole,the ruler falls out?** A: I don’t think the hole is for hanging. The plastic sleeve is to protect the ruler edges and printed marks from scuffs and scrapes, and the hole is to let a bit of air in so it’s easier to slide the ruler into and out of the sleeve. **Q: Will these ruler stick to magnet? I am looking the stainless steel that can attract to magnet.** A: Yes these rulers are made of a magnetic stainless steel. They are excellent quality. I am very pleased with my set of four. **Q: Are the marks etched on both side not just printed?** A: They are etched, and on both sides. These are a very nice set of Stainless steel rulers. I am completely satisfied with my 4 piece set from this seller. **Q: price for a case of them how many in a case?** A: Since the option to purchase a case was not listed on the information page, that would be a question for the seller, Mr. Pen, not the community of users who typically purchased the advertised four pack and can typically only share their use experiences. There is a Mr. Pen link top right corner of the page below Buy Now where you can submit a question directly to Mr. Pen. They will probably be thrilled to get an order for a case! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice thin markings, easy to be precise *by on Reviewed in the United States 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. ### ⭐⭐⭐⭐⭐ Quality and Highly Functional *by on Reviewed in the United States January 6, 2026* 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. ### ⭐⭐⭐⭐⭐ Rulers for your grandkids? *by on Reviewed in the United States May 11, 2025* Beautiful, high-quality rulers! Made of thick, sturdy steel (magnet-tested). Which is nice, since they don't have hanging holes, so you can use a magnetic strip. The markings are deeply incised and paint-filled, so they don't look like they'll wear off easily. They function great; the markings are accurate and easy to read. (Even has 64th and 0.5mm markings which are extremely close together and a bit hard for my eyes to read without a magnifier.) However, since they're relatively heavier than most rulers, they're a bit less portable. Also, the edges and corners aren't very polished, so they're fairly sharp. Might be a feature for some, but you can round them down if it's bothersome to you. Funny to say, but they're probably "heirloom-quality" rulers that your descendents will end up using. ## Frequently Bought Together - Mr. Pen- Machinist Ruler, 4 Pack (6, 8, 12, 14 inch), Metric & Millimeter Ruler, 1/64, 1/32, mm and .5 mm, Stainless Steel - General Tools 300/1 6-Inch Flex Precision Stainless Steel Ruler, Chrome - Stainless Steel Feeler Gauge Dual Marked Metric and Imperial Measuring Tool(0.04-0.88 mm, 32 Blades) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/207567487-machinist-ruler-4-pack-6-8-12-14-inch](https://www.desertcart.sk/products/207567487-machinist-ruler-4-pack-6-8-12-14-inch) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-14*
