This credit-card-sized motivational bottle opener is great for on the go situations.  Personally I do not put it in my wallet, as it is a little on the heavy side and I like to keep my wallet minimalist.  But it is a perfect fit for my zippered pouch in my purse.  The fum graphics remind me not to forget about working out (rarely do I need to be reminded to sleep and eat).  I received a sample of this product (either free or at a discounted price) in exchange for my honest review. All opinions stated are that of my own and have in no way been swayed.
