Also worth a look in this category:
Structure over thickness
A briefcase should stand on its own when empty. That comes from an internal frame and stiffened panels, not from thick hide. A heavy, unstructured bag slumps and creases everything inside it.
Laptop fit is not a size label
Measure your machine. A case built around a 15 inch chassis from a decade ago may not close over a current 16 inch laptop, which is wider even though the diagonal is close.
Care that actually helps
Wipe with a dry cloth after rain, never near a radiator. A neutral cream once or twice a year keeps the flex points from cracking. That is the whole routine for full grain leather.
