Perfect for quick watertight seal does not leak. Not to confident how I would be traveling around with it as the lid could pop open without too much effort. I needed them to hold a liquid and hand out worked perfect. Just wish they also had them in little bigger sizes as well because water tight vials for some reason is hard to find on amazon. Not really that great on prize either because I got 50 vials for the same prize they’re just not water tight and leak slowly. So these are very good for water tight seal
