Review on Protractor Designers Architects - Multi-Functional and Versatile Design by Darrin Parasson

I don't like this tool at all. I wanted to use it for zentangles. It's too hard to keep the center in place! Too small to be very functional! How much did I pay for this useless set? Why, oh why, I threw the box away. I would return it immediately. I have a drafting ruler and a Staedler compass that holds fine-tipped Staedler or Micron pens on the go!
