If you blend your colors directly into your finished nail polish bottle, a temporary cap such as our Shaker Top is a useful item. These Shaker Tops have a 13/415 finish. This size not only perfectly fits our nail polish bottles, it is a size common to commercial nail polish bottles such as Sally Hansen. While we can't guarantee a fit to the bottles you have on hand, the odds are good!
Why use a Shaker Top? We find that in the thrill of the creation, you can sometimes get color or fingerprints on a nail polish cap. If you are reselling or gifting your creation, a Shaker Cap can take your abuses and when you are 100% done, you simply replace it with the un-sullied nail polish cap with brush.
