This is my second parallel glider of this model. Made in Poland, extremely high quality. The only downside is that the rubber rings on the wheel mechanism seem to dry out over time. Otherwise it is almost a perfect piece.

Very happy with this tool. It is not flimsy, I expect it to last. Very smooth rolling. I am using it primarily for lining, but nice to know I can create circles with it too. I've seen it priced for more and am feeling that I got a good value from Dew Drafting. Arrived quickly and I've put it to use right away.

I've had an inferior rolling ruler for a few years and was frustrated each time I needed it because it doesn't roll straight so it basically defeated the purpose. I finally splurged and got the Alvin and it's like night and day. Plus it can help you draw circles and angles (who knew?). I'm very happy with it so far and look forward to using it on lettering projects for many years to come.

There are several less expensive rolling rulers available and I have gone through 3 of them. This one however is made to last for a while. The clear "ruler" portion is thicker and rigid. The roller is metal and perfectly straight yielding accurately parallel lines when you need them. The right angle measurements at the corners are a bonus and a time saver.
