Just pulled out my mono speedy 35. (Almost 2 yrs old) It's not like yours, but I think with DE it's more noticeable since your leather is treated
Yeah the DE is always prone to wrinkling. Can't really prevent it.
Thank you for replying. Are your DE speedy b's handles like this?
I wouldn't say wrinkling of leather is a flaw, but an ageing process that shows it has been a well loved and a used bag.
