Accurate and easy to read
Very nice ruler, high accuracy (JIS Grade 1, traceable to the Japanese national meter). It’s easy to read with the non-glare surface and clear ticks/numbers. Mine is etched Made in Japan. Some reported the conversion charts were smudged or it was hard to remove from the sleeve, but mine was fine on both counts.

a solid piece of measuring equipment.
I think this is like the third or fourth time I've bought this exact item. It's just such a useful tool, I've gotten one for the sewing room, one for the leatherworking table, one for the computer desk, etc. I like buying Japanese tools, and Shinwa is a top name in the measuring business. The ruler is made from a sturdy piece of steel, thick enough so I'm not worried about bending it. Every 50 mm is marked in red, which just looks nice. One edge is marked in millimeters, and the other edge goes down to half millimeters—the first edge is easier to use day-to-day, but it's nice to have the other edge for precision when needed. Most importantly, the measuring starts from the edge of the ruler. If I had a dime for every time I've measured something with another ruler only to later notice that the "0" was like three millimeters from the end…well, I'd have like 50 cents, but really, all rulers should emulate this one and have the measuring start from the very end!

easy to see, precise ruler
My partner works for a company that prints and binds books on demand (POD). He needs precise measurements for the spines of the books. This metal ruler is easy for him to see under the industrial lights of the warehouse. The quality is great.

Very Good
Excellent 150 mm rule. This is super handy for precise, short measurements. The one I received was made in Japan. Both edges are marked. The half-millimeter marks on one side of the rule are probably beyond the precision I will need, but it is cool to have them. I like the plastic sleeve.

Not quite rigid, actually
Nice enough quality for a ruler but not really rigid, which is what I wanted. I did return it.
A**!
NICE!!!
Use it at work, I'm a machinist, and this thing is quality. Nice and straight - no annoying bend to it, clear markings, good thickness, hard to go wrong for the price. Wasn't sure if I was going to like the curved end without markings, but it's not an issue at all.
