|Bad brushes from OPI and Spoiled|
I've reused my empty bottles for other nail polishes by simply filling the bottle with acetone and shaking it. Doing this, all the old polish gets dissolved and the brush will be cleaned of any polish residue, especially if you do it more than once. You can do this again right after reusing your brush with a new color to make sure you always have a good quality brush-for those colors you love with brushes you hate.
|A couple of the empty bottles I keep for their brushes|
1) Sharing nail polish. See my prior post here.
2) Creating your own frankens. You need an empty bottle to pour all your mixture into!
3) Worst case scenario: a bottle break. I've seen a few pictures online of people whose polishes have broken- because of bad shipping or a bad accident. In some cases, you may be able to "rescue" some of the polish in the broken bottle by pouring it into another bottle right away. The pictures I've seen where this seems like a possibility is the cases when the bottle breaks near the neck. You would just pour (as carefully as possible, because broken glass is involved,) from the broken bottle into the empty old bottle. It can't hurt to have an extra bottle around, just in case!
I hope this post has made you reconsider throwing out your empty bottle of basecoat or polish. It's still got the potential to be a good tool in a nail lover's arsenal!
