SquareHue: $21/month, 3 polishes, no selection. Each month you receive three regular full-size polishes around a theme. Your polish stays up-to-date and right in fashion just by subscribing.
3-free & camphor-free nail polishes (I think that makes it 4-free?). Donates to great causes, not tested on animals, and made in the USA.
This box sells out quickly. If you are interested in the box, snag it while it’s available.
