Clips are handy, Ideal for thin liquids, but no drip seal [SEP] We travel a fair amount and have quite a collection of these silicone travel containers - these are pretty much par for the course although they have a smaller-than typical hole which makes them ideal for thinner liquids like hand sanitizer, and they also don' t have the silicone valve to prevent drips.<br /><br />This still makes them ideal for thin liquids like hand sanitizer or something like face cleanser.  The metal clips are also excellent - I use a hanging organizer so this works well.
