Hi there Doc! I've been amazed at all the knowledge you have and been trying to use the standard recommended moisturizing treatment with Blackrock! I just treated a new to me box Kelly and noticed where the leather bends when you open it up there looks like some minute creasing/straining... I tried to capture it in the photo. After 2 treatments, maybe it's still dry? I figured before going further that I should ask for some advice though! Should I do another round of Blackrock or any other wisdom for me? Thanks so much!!!
