Great for geometry class with small drawings. Great price!
Comments about Westcott/C-Thru Westcott C-Thru Protractor Ruler:
Students will abuse this, like all bendable rulers. The price makes it heavensent. I've been using these in class for four years and went to reorder from A-Prime two years ago. Their price almost made me quit teaching. A little work on Google and now Bilck has my business.At this price it's acceptable to go through 40 a year and write it off my taxes. Big difference - same ruler.
Bottom Line Yes, I would recommend this to a friend

Replacing an old lost classic
from Nampa, ID
Use these in teaching my geometry class at a high school, lost my other one. Reason for 4 stars is one of the rulers had the printing on the face slightly of from square, so not perfect, but very close. Otherwise, this thing gets 5 stars.
the angle of things
from Grinnell. Iowa
I use to mark angles and degrees on some of my blueprints -(sketches or drawings) for the projects to be done.Being see threw makes it easier to see where you have been and where you are going with the lines to be drawn.It is a little to thin for me maybe make a thicker version of it would help.
from potsdam, newyork
it is two in one instrument in flexible plastic. good for geometry works. if the length measurements are given in color other then red, it would be great. i had little difficulty reading it,as i can't see well. even though, great math instrument

A really good one to have
from Charlotte NC
This product is a must to have for art designs and room planning for Home Interior Designers, and Fashion Designers, the increment on the ruler is just right for minute details, and for room planning those 3" walls, the circumference is really good for exact models. A well valued purchase!
