Mix & Save ($2.49 for a pkg of two; 8 containers per link):
What I like about it: I personally like this one better. The a row of containers are linked together, so you don't have a bunch of jars to sift through. The containers are translucent, so you'll be able to see your color and air tight when closed. Great for traveling. I can consider it almost like a palette for your pigments or mineral makeup eyeshadow. The connectors that link the containers together are not flimsy at all. And it's cheap!
What I don't like about it: You can still make a mess when opening it. Since the caps close tightly, if you fill up the container up to or a little bit before the rim and pop the lid off, it can get messy (so I suggest you don't). You have to be careful when you open the container since you're simply not unscrewing the lid. Also, since the containers are linked together if you have more than one container open, then you have another opportunity to make a mess. Lastly, the hinge connecting the cap and the container may break after awhile since it is plastic, but that's a very minor problem. If it does break, you can just cut the excess plastic off.
Buddy Caps ($3.49 for a pkg of 12):
What I like about it: This one is a bit bigger in size compared to the Mix & Save container. This is also airtight when closed, but it's not linked together. The container is also translucent for easy viewing of your pigments or mineral makeup. Still great for traveling.
What I don't like about it: The lids needs to be popped off to open.
Contact Lens Case:
What I like about it: You can find it almost anywhere.
What I don't like about it: You can't see the colors inside.
And when foiling your eyeshadow, you can use a painter's palette ($0.69). It'll keep your eyeshadows fresh since you're not directly dipping a damp brush on your pigment or mineral eyeshadow.
