Sorry if my pictures aren't perfect -- not too used to taking pictures including my thumb also, had a hard time arranging my hand, haha. So when applying Black Spotted, you definitely need to make sure to use an almost absurdly thin coat -- basically don't have any polish on the brush, and you're good to go. Otherwise, it won't bubble really and will just be black. Also, the wear isn't that great; if you don't topcoat it it will kind of flake off almost immediately, and even with topcoat my tips suffered pretty badly within like 12 hours. All in all kind of a pain but the effect sure is fun! And I always love rocking a skittles mani :)
Like I said OPI Black Spotted is HTF, but you can find it on eBay for not too terrible prices. Also, I saw that Layla came out with a new Bubbly Effect line that is likely similar -- can't wait to try those out myself!
Have a great day! ♥
