It comes in a box containing two smaller boxes. Each smaller box contains one bond touch bracelet and one charger, in addition to a set of instructions. All in all two (2) bracelets, two (2) chargers, and two (2) sets of instructions. You’re told the battery will last around 4 days, and that may be true with significantly less use, but I would say if you’re going to use this semi-regularly, you’ll need to charge it every 2-3 days. Also, once you slide (Don’t pop it on) the charging module on the bracelet, and plug it up, it takes around 30 seconds before it starts flashing the first time, so don’t be alarmed by that as I was. My girlfriend and I use this often and we both love it. We’ve come up with our own code based on the number and longevity of the buzz(es) we send. I do highly recommend this product, and say you should have nothing to worry about. It’s a good purchase.
