I've not seen the turn lock WOC in person yet. As someone who tends to stuff it quite full, yes I use it as a BAG, I am worried about stretching out the lock. Hear me out. I have had turn lock purses in the past and it would get to the age or the leather would stretch over time and if I did not put in enough to fill out the bag, almost as if the contents had to put some stabliziler impact on the lock from the inside, I had trouble turning the closure. But I may be overthinking this, a WOC is not large no matter how much I can fit into it.
Hence my personal apprehension of the turn lock version...but yes I still want to see one and try it!
