How much were the tattoo bags when you went?
They didn't have any of yours as I think that's a new, limited release. They had older styles between 185-250 if memory serves.
They are definitely bags that you don't have to be delicate about. I've only been ultra careful with lighter leathers. I'm normally careful anyway about where I put my Koobas and I never carry loose items that would mark or damage it (pens, makeup, etc).
Sorry about getting off topic! Maybe we should start a Kooba vs Other Bags post?
