Items arrived without damage, in the estimated time for delivery. Items are just as advertised and all the basic features of the speed squares, plus other features one may do with a speed square. I expect to use these items for a time. But if I loose one or both i will order the item again. Thanks for good purchase experience.

A really great value and quality speed squares. The large one is metal with the smaller being plastic. Between the two it should cover most of your needs. Both are well marked and easy to read. I would buy again and definitely recommend.
