...a BAR code.
Today's nails are inspired by UPC codes. They're on EVERYTHING we buy, no matter what. I'm a total shopaholic, (If I were a dinosaur- I'd be a Shopasaurus Rex) so I see these bad boys on a VERY regular basis. I used to have to create them at my old job, too, so I'm fairly familiar. I couldn't fit an entire one on a nail, so they're just bits and pieces, buuuut, yeah. :-D (I wonder what these nails would cost if they were whole bar codes?!)
I used Sally Hansen All the White Stuff as a base, with American Apparel Hassid for the bar codes. Topped it off with 2 coats of Seche Vite top coat.
