Once open these things can be a big headache especially when you only use small amount on small models.
Please share your ideas and pictures could come in handy too!

I was thinking I might use something like a bulk CD case.

Thank you Randy!
Of course that was the first thing I thought of but When I thought it, it just seemed like there was something better way. after more thought about the CD and how I would need to make a spacer because the hole diameters are different, Stacking them one on top of another, having to dig down to get the right size... far too complex all around.

Just put a piece of the tape on the front to see the color and the size. 

Why does it make more sense when you say it?

The only problem I see is air can still get to it in a CD case, but if you use it fast enough it wouldn't matter.
