Cosmetic containers can be used to store everything from small craft parts to extra water based paints. Many of the larger cosmetic jars can be used as canisters for certain dry goods in the kitchen or made into a decorative accent. Though air travel requires sizes within certain specifications, the sizes of cosmetic containers are varied from small and stackable to canisters for toiletry items such as a cotton ball jar or sundry jars for things like cotton swabs and make-up pads. Clear plastic or glass cosmetic containers also help you identify the contents quickly while you are away. That same reasoning applies to using the cosmetic containers that are clear glass or plastic at home.
