### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Thick rigid square edges nice case
  

*by J***N on Reviewed in the United States on March 22, 2024*

I got these to do lay out lines for calligraphy. They are 1.5mm thick and quite rigid. Easy to hold and make a clean line.  They are perfectly clear with sharp markings.  The case is exceptional.  Sturdy with good hinges and latch. There are stops inside to hold the pieces in place.  Very pleased.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great
  

*by K***G on Reviewed in the United States on August 28, 2022*

This is a great ruler set at a great price. Really deserves more attention on Amazon. Maybe because it is in metric units only.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Great Ruler Set :)
  

*by A***Y on Reviewed in the United States on March 30, 2021*

I've had this ruler set for a year and half now and it is in good condition. Shipping took a while at the beginning, but I did receive the package (3-4 weeks) and it was in the plastic wrap it is pictured in, undamaged.The only downside is that the bottom is slick like any plastic ruler, so I'd recommend putting something underneath so it doesn't slide as easily and potentially be lost.
