These protractors work well, and are small enough to fit in my workbook so I can draw the angles right in the book. Compact size but clear lettering.

good product

Nice Product. I bought the six inch protractor to use for drafting patchwork designs. I like it because there is a ruler on it in inches (although upside down for me) and one in centimeters. I also like that there are markings on the inside of the curve as well as on the outside. It is not as robust as the Helix protractor but will be very useful to me.Unfortunately, I have no use at all for the four inch protractor as I still have one from my long ago school days. Too small for my needs now but someone may appreciate having both.
