I was skeptical at first because I'm looking for was on the to spice jars that prevent the spices clump, spezill garlic powder and paprika and fine ground spice mixes such as China spice were mostly no longer gebaruchen in their original box after 2-3 months. These spice cans but that does not happen, because they include 100% leak-proof and which could become brittle without condoms. well would be only an additional stray paper, so you do not jedesd times a spoon etc. required.
