This is a great idea! I have over 100 loose eyeshadows and pigments, and still adding more to my collection. I've depotted most into the commonly used "darice Bead organizing "containers with 24 jars. And they work great, hold my pigments beautifully. Although ,I do wish that I had done better research, because, health wise, these aluminum containers are better for keeping out germs and very low to no bateria growth. As opposed to the plastic ones. But The price is also a factor. Aluminum ones are a tad bit more pricey. It's just up to you, wether you want to make the investment to aluminum , or just get plastic.
Either way, depotting your pigments makes it easier to see the color, can access the product better and is easier to store!
Wish you the best in your cosmetics!
