    Nice ruler
  

*by N***A on Reviewed in the United States on 21 November 2023*

    good for college students
  

*by S***L on Reviewed in the United States on 21 January 2024*

has all the desired measurement lengths. good for construction management students or anyone else.

### ⭐⭐⭐⭐⭐ 







  
  
    Love the colored sides for reference
  

*by D***Y on Reviewed in the United States on 8 December 2023*

Nothing special but my old scale broke and this one has a colored groove on each of the three sides - red, yellow and green.  Once you remember which color is on the side with the scale you want to use you can pick it up and go to work without flipping it over multiple times.
