Mr. Pen- Small Scale Ruler, Architectural Scale, 6 Inch 2 Pack, Pocket Size, Engineer Engineers Ruler | Compact Measuring Tool for Drafting, Drawing, School, Office & Design Work

Awesome little rulers. They fit in my drawing case perfectly. love them

Small, practical, and really well made! Perfect for keeping in my pencil case or desk. Great quality from a reliable company, I love it!

Sometimes you see a product picture and it’s obviously photoshopped into whatever scenario the picture is depicting. I saw these scales and was like “no way they’re that small”, but they are indeed that small! Perfect for me to carry around in my pocket at work. They’re the width of chopsticks, ink pens, pencils, other things of the same size (you get the point), and they’re super lightweight. A downside is the readings are also small. If you need to use this more often than every once in a while, you probably want a bigger scale, but for me it’s perfect. I’ve bought Mr. Pen products in the past and I like the variety of things they offer. Everything I’ve gotten from them feels sturdy and well made. Their prices won’t empty your wallet and you get a mustache sticker with every order!

These are useful but I find them a little too small, particularly from a handling perspective. If you've got young nimble fingers the size might not be an issue.

Keep one of these in each of my journal pouches. Perfect for precise drawings on grid paper and a compact size.
