Our set contains 12 black empty aluminum cream jars. They are made of aluminum that will not rust, food safe, non-toxic, odourless and environmentally friendly. Each waterproof can comes with an airtight screw lid lined with a foam insert. This means that your lightweight cosmetic jars are leak-proof and your contents are also protected from sunlight and dust. Use these small containers with lids for all your homemade cosmetics, such as lotions, creams, ointments, as a lip balm jar or for powder. You can also use them as candle containers or for samples. The tins are refillable and can store food such as herbs, spices, sweets and tea. As our metal tins with lids are lightweight, they are also perfect for taking with you in everyday life
