I liked the last 17 magnetic polish so much (see here) that I got another one.
This is the dark purple version. It's called Lilac, I'm not sure why, as it really isn't lilac in the slightest.
Application was good, exactly the same as the green version. This is two coats - one coat on all ten nails, left to dry, and then one nail at a time adding a second coat and holding the magnet above the nail.
This dried quite matte and a bit dull-looking, but once I added topcoat, the shine is gorgeous.
