Mr. Pen- Metal Straight Edge Ruler, 4 pcs, 6", 8", 12", 14"

These are great! I was unaware of the "Mr Pen" brand previously, but these rulers are perfect. I was replacing a metal ruler that lived in the kitchen drawer but was repeatedly used by the kids (and often not returned). So I got this set to both replace the large ruler in that drawer, but also provide me with some smaller ones I can use to quickly measure things involved in my 3d printing hobby. These are perfect. When I need larger, I have a metric tape measure, but for hand-sized objects these are fantastic and have .5mm marks for the first 2cm. I love that there is both metric and imperial and that there are different sizes for different uses. They seem accurate (I don't have a reference gauge to scale against, but their measurements, when 3d printed, align with expectations). They are sturdy. They are easy to use and store. And I was even able to provide one to my daughter to use when quilting. She uses the metal edge as a straight-edge for cutting straight lines and guiding scissors and rolling cutters. These don't have a non-skid surface, but instead include a very handy conversion table on the back side.Overall, I'd buy these again from this brand if these 'walk away' when my kids use them. Great value, great product.

I just got into 3D printing. Almost everything is designed in metric dimensions, and I am not well versed in that area. I had a few relationships in my such mind, such as a 13mm socket is 1/2", that sort of thing. But I wanted to get more familiar with other similar sizes. I figured these rulers would be a great help since they display metric and imperial on the same side and very handy conversion tables on the other. The markings are etched and very crisp and clear. They should last a very long time. And of course the stainless steel is always a plus. This 6 pack was an excellent value and I recommend it. Update: I wanted a case to hold them all, so I 3D printed one. Update 2: I wish they started at zero instead of having an offset. You can't butt them against an object to take a measurement. I'll probably cut or grind the end off.

purchased these for my sons engineering class and I like that they came with multiple for the price. sturdy good quality

Pros: Lightweight. Good quality. The markings are not just stamped onto the surface; the rulers are engraved and the black enamel is in the engraving, below the surface. There are conversion tables — imperial to metric — on the reverse side. Though very small on the two sizes I purchased, it is nonetheless handy.Cons: The edges all around are not at all smooth. The corners are especially sharp. I could easily see these rulers drawing blood. I would, therefore NOT recommend them to children younger than pre-teen.Conclusion: Good rulers, especially for the price. The set of two I purchased are very handy sizes, and will be used in my sewing room. While it shouldn’t be necessary, I will smooth out all of the edges and corners on various sizes of sandpaper before using them around fabric.

Exactly what I needed!! All my rulers are either silver metal with black print or clear with red print. Both of these are very hard to read. These new rulers are perfect with black metal and white print and are great for my aging eyes. They are nice and flat and made well.

Prroduct as described. Met more than my expation. 😀

Excellent for Using them as knife guides when cutting straight edges on paper or cardboard. They Excell because of their thickness, easy readability, AND their ability to hold onto the paper or cardboard WITHOUT SLIPPING! Once you put them down, they stay put. They have a Very slight but effective edge on the bottom that grips without making any impression or marks on the paper. The set is magical and is now my favorite. A wonderful variety of sizes, each as perfect as the other, and sturdy to last without bending. Excellent quality.I have many rulers each with problems. This SET is perfect - both readable in inch & metric - no upside down reading and deeply incised so no wearing off. Being Non-Slip is so helpful - your careful placement doesn't slide!! So many great sizes gave me luxery of the right size for different crafts. They greatly improved my bookbinding cuts and sewing markings.Such a great deal for Perfect Rullers. THANKS

Quality is EXCELLENT. Price simply can't be beat. Very nice company - love the little moustache sticker they put in every package. I've purchased from this company before and their quality exceeds expectations, especially for the price. These rulers are easy to read, not flimsy and the conversion chart on the back....come on....what a nice bonus. I purchased these for my baking and kitchen use and each one comes in their own little sleeve. This is a company with integrity that takes pride in their work and puts out nice, quality products.

all good but i didnt notice inches are on the top side and cm under...I would prefer it opposite

The rulers were good and satisfied my use case. I needed two sizes only, but getting that pack was welcomed as now I have spares as well if I need them. They are a bit rough on the edges and might bite on a soft crayon or something else one would use. I use markers, pens and pencils and also knifes for cutting and they work well for these purposes. Generally I would recommend them. Especially for their price.

The variety of sizes makes it easy to carry.

These are perfect for my card making hobby. I love that there are different sizes too.

Arrived well wrapped and on time. Great set of rules for the garage workshop. The smallest I have used a lot! Great for setting up machines. Makings are precise.
