I found them on eBay, and there were very reasonably priced. (See, fun nail art can be totally affordable, folks!) Five of them came in the package and they are made of plastic and have metal tips on both ends. One side of the tools all have the same size of metal tip and the other ends have 5 varying sizes of metal tips. They seem like they will be very versatile for different sized dots - I can't wait to experiment!
The tools actually seem quite robust considering their price, so I am curious to see how long they last. I'm keeping it pretty simple with this manicure, but I love the delicateness of the line of dots. I used Essie's Sand Tropez and Turquoise and Caicos.
Such a sweet colour combination - so perfect for Spring!
