Adding the chain actually doesn't look that really, I don't see it taking anything away from the looks of the bag in general. I'll have to look for some chain now.
Thanks! Ball chains are pretty easy to find at hobby and hardware stores or online, and you can cut them to length.
Or you can borrow the hangtag chain from another bag to protect a fob - but then you have to remember to put it back later! Zip the hangtag securely inside the inner pocket to keep it safe and handy.
And if you are moving hangtag chains around, remember to give the latch a gentle squeeze with a pliers to keep it snug.
