I had a Castillo case several years ago and honestly it was a seriously well made piece of art.
I am a leather guy, so I am not into decorations and tooling. I look at the quality of the leather, the stitching, and general execution of design. The one I had nailed every point. It was a seriously well crafted piece made with absolutely premium materials.
Your post reminded me I had one and sold it. I regret it. I should get another.
