My current stash in photos:
Ulta3, BYS, Sportsgirl, Revlon, Rimmel and Essence.
China Glaze, OPI and Colo
Random polishes, top coats, base coats and treatments.
I use Homemaker brand single drawer units from Kmart, which cost $10 each. They will hold between 45 and 60 bottles of polish depending on the size of the bottles, and are stackable. My dotting tools, nail art brushes, rhinestones, nail polish thinner, Konad supplies, nail polish remover, cuticle sticks, buffers, files and the like live in a plastic food container.
