great for lip gloss powders or glitters [SEP] these little containers are perfect for your lip gloss powders and glitter definitely not leak proof so you do not want to put any liquid in them they would be okay for traveling but to small to really put anything in if you are planning a long trip the are sturdy but if you step on it or throw they definitely will break i was disappointed in the packaging of them plus i was missing a lid to one container and one whole container
