Unlike its all-plastic peers, it's durable, high-quality, and precise. Here's why I love mine:

  • This parallel glider is great for drawing calligraphy and lettering guidelines, slant lines, and hand lettering. I also use it often for illustration.
  • The aluminum base with non-skid rubber wheels ensures a smooth glide up or down.
  • The crystal clear acrylic makes it easy to see what you're doing.

]]> I’ve searched high and low for these parallel gliders to stock them in the TPK Supplies Shop! It was almost impossible to get a hold of them in 2020 because Alvin, the manufacturer, went out of business. In 2021, another company acquired the rights to manufacture the parallel glider (/”rolling ruler”). I’m pleased to say that the new Alvin parallel gliders are identical to the original parallel glider that I fell in love with in 2014. (I’m still using the same one!)

A parallel glider is a bit of an investment, but it’s a tool you’ll return to again and again, and it lasts for years. If you’ve been using a parallel glider with a plastic base, you’ll be amazed at what an upgrade this aluminum-based beauty can do!
