Pens and other items like drinks or snacks are of course a concern. I totally understand why some people choose not to carry them especially in really high end bags. Generally, I treat my bags with care but use them for everything as I want them to be practical and get joy from carrying them. I do put drinks, pens, hand cream etc in my bags but often in liners or pouches for the pens and hand cream. I check bottle lids really carefully!
Maybe I’d feel differently if I owned some of the Chanel or other high end bags some members have.
@Katinahat I do relate! I really cherish the German vintage bags I use all the time (like Goldpfeil or Aigner or Jaguar) and am careful with them, but don´t think twice about pens and handcream I need (in puches!) or food my son passes to me for safekeeping (there´s always a plastic bag at hand!). These bags don´t mind being used and stuffed to the limit. If I had a Chanel or other really high end bag I´d certainly act differently.
