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 dripsthis 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
