I don’t own any high-end 1-2-3 blocks, setup blocks, etc, so my impressions are amateur at best. They seem to be precisely 1” x 2” x 3”, measured +/-0.001” with a caliper.The finish is smooth to the naked eye, and the wood box for storage is a nice extra.

Exactly what I expected but the nice case was a bonus. My old ones came in a hardboard sleeve. A wood box is nice to have.
