This is the third (and final!) Metallica polish I wanted to show you. They aren't really the sort of polishes I would wear as a base, but they work so well for stamping!
The base is Color Club Take Me To Your Chateau, stamped with Athena and PUEEN13. This is a fairly thin, delicate stamp, and as you can see it stamped very nearly perfectly!
You can buy 2true polish from Superdrug. The Metallica range are £4 each.
