I don't know why people hate on crackle so much, but I'm glad cause I really like this look and it's always super cheap cause nobody else buys them ;)
For me, crackle nails are an instant nail art look without much effort and if you use fun colors like these ones it can turn out pretty cool
For these I used Kleancolor Pastel Purple and LA Girl Fracture. I wish I had better pictures of them cause they were pretty fun and cute.
