Nail stamping is a quick and easy way for nail art. I purchased these nail stamping plates from Amazon.com and am truly impressed. I used a base color of Sephora's I'm Seeing Pink Elephants, which is a nice cotton candy pink color. For the white I used a nail polish I purchased at the Japanese dollar store (Daiso). The white polish is on the more transparent side. I wish it was more opaque. If you purchase the Konad brand polish it does a much better job. The stamping kit I purchased on Amazon also, it was originally ten dollars I think, but now its only $4.50. The reviews are kinda bad on it but I think it works great.
