Both the Dublin and Derby leathers are considered to be within the Essex line. They have an almost identical tannage with slightly different finishes. You can count on the Derby and Essex having smooth finishes, while the Dublin tends to have a waxy finish.
These are Horween 2nd run leathers which means they can have some issues such as healed scars/scratches, drawn grain, loose break, brands, etc. These sides average between 18-22 sft per side.
