I am guessing that the owner has been shortening the chain under the flap by pulling the chain from the two ends of the leather tube and then tie it together ( like create a hidden loop ).Hello does anyone else’s wallet on chain look like this? What causes the leather where the chain is to crease/wear down like this? TIA! This is from 2014.
But the own pulled / tied the chain too tight that it damaged the two ends of the leather tube.
