I don't have BF bottles, but we have the inchbug bands and they fit on just about everything. I've used them on regular and wide-neck bottles, sippy cups, snack traps and water bottles. They are quite stretchy so I would think you will be fine.
I was googling and found this and i wanted to tell you that YES! They do. We use the born free glass with inchbug labels every day at daycare. So friggin handy.
