For swatching sake I popped China Glaze Crackle Glaze in Lightning Bolt over top of China Glaze High Def.
These crackles take such practice to get the thickness you want. I start painting at the pinky and work toward the thumb, and as you can tell from the pic, I don't hit my desired thickness til about the pointer finger.
Lightning Bolt is like painting your nails with white out, except it's obviously going to crackle as it dries, which is immediate. I'm not sure LB ranks well in my polish stash, but everyone needs a white crackle in their life ;)
Retail on these will vary, it just depends on where you buy your China Glaze!!
