Customer Reviews (3.8 / 5 · 5 reviews)

Victoria E. ★★★★★

I was pleasantly surprised how well this fits in my shirt pocket—the 3-3/8" x 7-9/16" size is just right. The plastic feels sturdy enough for daily use without being bulky.

Lily ★★★★☆

The oil and grease resistance is handy for a garage tool, and it's slim enough to slide into my apron pocket without bulging. I just wish the markings were printed a bit bolder for low-light jobs.

Elizabeth ★★★★☆

The pocket size is perfect for keeping this in my apron, and it held up fine after I wiped some oil off it with a rag. Only wish it had metric markings as well as standard.
