Great, was just what I needed. Perfect weight so that it doesn’t budge as I draw along. Nice and durable, serves its purpose.

  • Nice But Reflective
Color: Black
I bought this to use to sell pendants on eBay to show the dimensions. It is nice and works well, but it is reflective, and so you can see my reflection in the pictures or reflections of a nearby window. I have spent a lot of time removing my image from the pictures and also removing dust which shows up quite noticeably. If you intend to use this to photograph, just be aware of its limitations. Edited to add: the seller contacted me and resolved the issue for me, and so I added a star for great customer service. ... show more

  • Keep the mustache stickers coming Mr Pen!
Color: Black
This is the 7th Mr Pen product that I have purchased over the past few weeks and I have yet to be disappointed. Quality is never sacrificed in keeping these products affordable. This t-square is a perfect 90 degree angle with accurate measurements and of a strong, straight metal construction. The numbers are easy to read and, due to the fine craftsmanship, I look forward to these measurements remaining visible and intact for years to come. ... show more
