Glass bottle with fine cap brush?

Thanks for the link. Too bad that they don't sell in a small quantity. I've found that two of my wife's nail polish bottles have very fine brushes. I might hunt for empty nail polish bottles.

Does anyone know where to get small glass bottles with fine cap brushes?  I've seen a few on eBay, but the cap brushes are relatively thick. 

Here's a link to a lab supply where you can buy thin brush caps and bottles - just order plastic or glass bottles to match the caps.

I ordered from them once and got great service.
