Review (5/5): Small enough for airlines and trips to the store, great clip, good caps
I bought these to fill with hand sanitizer and keep in my coat pockets (I'm in the NE so I don't go out without a coat). When I get home, I'm never in the same rush as I am when I leave, so I make a point of refilling them and replacing them as part of my get home routine (bring bags to the garage, wash hands, clean stuff in the garage, including sanitizer bottles, wash hands, refill sanitizer bottles, place in coat).
I use enough hand sanitizer that these small bottles are good for two days, at best, often just for one, but with my routine that is just fine. The bottles open and close easily and the caps fit tightly. The top is wide enough to fill easily. I've used the clip which is a good clip, but I generally just keep them in my coat pocket. I've not had any open accidentally nor have any leaked.
I'm very happy with this find.
