Review: Great rulers - accurate and clear - 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.
Review: Nicely etched and a great value for six rulers. I'm not crazy that they don't start at zero. - 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.
