great solution for those with bulk hand sanitizer who want to bring it on the go [SEP] i got these to clip to my bag i kept losing my hand sanitizer i really like the style of the kinds that clip to your bag with the silicone jackets but the inside is still plastic and they are not meant for long term use enter these guys you can refill them from your bulk hand sanitizer at home and you never lose it and it does not take up valuable space in your bag have not had any issues with it leaking or the top popping off i would not use these for edible items though and i would suggest that you run them through the dishwasher firstthey do have a very faint smell but not as much as some silicone things i have gotten on amazon overall a great buy and solution for bringing hand sanitizer with you
