    • Solid, accurate and easy to work with
Color: Black
This carpenter square is durable and very accurate. It’s a bit heavy, but that actually makes it easier to work with since it stays steady in place. The markings are clear and the overall quality feels reliable. Great functionality, strong durability, and good value for money.

    • Good Value
Color: Black
Nice quality carpenter square. Good for DIY projects around the house, would be probably too small for any serious work. Well made. Satisfied with it. Absolutely, nothing to complain about, good to see how nicely this was made.

This square is solid, clearly marked, and accurate. I’ve used it on several woodworking projects and it holds up great. Perfect size and weight—not flimsy at all. Great buy for DIYers or pros!

    • 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
