Great for hand sanitizer [SEP] These silicone bottles are super easy to open and fill. They can then be clipped onto something like a back pack or a purse. I have one with hand sanitizer that stays on my purse. I have learned to be careful when opening them to dispense product. They squeeze really easily and I have gotten way to much product before I learned to be careful.<br /><br />I like that they come in a set of different colors to share with friends or simply use for different things.
