...storing small bottles of airbrush makeup?

Allison, I use Temptu S/B exclusively... and fortunately Temptu is now shipping product in clever lit' clear zip bags (8 bottle capacity)  That said, I have totally fallen in love with lit' plastic storage cases (available from Micheal's or Office Depot.  they are rigid, rectilinear and stack-able... 15 (3x5) bottles are a perfect fit...

Love them since I can invert the entire container every couple of days to keep the pigment nicely suspended... works for me   typically 15 bottles will provide the necessary diversity for a gig,

btw, love your wigs Allison, you're a gifted talent...  Since I'm a team member for the Glam Squad which works with cancer survivors I've come to truly appreciate the considerable worth/value of quality crafted wigs...   

Hope this helps
