Along with poor craftsmanship I don’t think the smooth leather is of the best quality.
I’ve got the Dix and the Huit, both in grained leather and they’re well made and hard wearing. That’s what is so annoying - they CAN do better, and the designs are fantastic. They just need to get their act together. I don’t know if it’s because their popularity has grown and they’re rushing to meet demand. Demellier have had similar issues too.
