I went out yesterday and finally bought a decent rack to store all of my nail polishes. (So happy!)
It's pretty big, has 4 levels of storage and it wasn't that expensive, around $24.
I still have plenty of space for any new nail polishes, tools or whatever nail related stuff I buy in the future, which is great because if you are like me, you can never stop buying new stuff.
The only downside is that it doesn't have wheels, oh well can't win them all.
