Walmart sells them sometimes. China Glaze has a line and Sally Hensen too. The brand I own is called Nabi and i get those from a little beauty shop across the street from my apartment. So if you have any little shops like that near you i would try those because you can usually get stuff like that cheaper :) and if all else fails, try the internet. Alot of websites such as amazon or ebay sells the for sure. if you do decide to try them the only thing i can say is it does take some practice to get the magnet right lol but once you find your rhythm its worth it :) I hope this helps ya hon :)
yep :) they are a little pricey depending on where you find them but they are cool. And you can wear them as regular polish or do the magnetic design by holding the magnet over the polish while its wet. :)
