Now here's a girly gadget I can really get behind! A good friend of mine gave me a bottle of Lancôme Le Magnetique Bordeaux Esmée, Star Design.
The varnish has metal particles in it and when you apply the second coat, you hold your nail up to the magnet on the bottle and a crazy star burst design appears! So cool! Check it out! Unfortunately I am late to the party on this because it doesn't seem to be available anywhere but ebay!
