### ⭐⭐⭐⭐⭐ Love it

Really great tool to have. A little more affordable than in the office supply store.

### ⭐⭐⭐⭐⭐ Architect's Scale
*by C***K on December 31, 2025*

Prompt shipping. Very nice scale.

### ⭐⭐⭐⭐⭐ sharper image couldn't do better
*by L***M on December 10, 2024*

Having signed up for a scenery painting class, one of these was required to do scaled reproductions. I've never used one before but found the look of this to be high quality. My instinct was right. This heavy, aluminum ruler is easy to read, feels nice in the hand and stands up to a bit of wear. Highly recommended for practical use.
