There are several ways that you can store your mineral makeup samples. However, my two favorite ways are in small 5 gram jars, or as I just finally tried, in a binder.
Here’s my binder
Binders are pretty inexpensive, and so are sheets to fill the binders.
5 gram jars can usually be bought for anywhere between .30 and .50 cents.
You can also go to Michael’s and buy little containers that are very inexpensive as well.
I use these usually for custom mixes that I make.
