I wanted to complement buying some 1-2-3 blocks for the basic layout. I searched and searched for something affordable that was accurate and looked good on the bench. These fit my needs. Very nice anodizing. good inch scale on one leg and metric scale on the other. I can't tell if the etching is laser engraved or screen printed. So far there have been no labeling problems. They seem accurate compared to my other scales. Extremely packed in styrofoam. It took a while but they will do what I need.
