Can anyone tell me how the glazed leather holds up over time? Does the "sparkly" look tone down with use? I have a MAM in glazed persimmon and I love the pop color for hot summer days but am not so fond of how it "sparkles" in the sun. I am considering returning it I but hate to give up the beautiful deep red/orange color. If someone who has had a glazed leather RM could tell me how it changes with use and time- or doesn't change at all- I would really appreciate your help.
