These are the Sephora by OPI Trend Tips limited edition Betsey Johnson "Skulls." They are mainly silver and holographic while the skulls are a darker grayish green color.
I am not wearing any top coat here, which I must say turned out to be a major, major mistake. I have a little tip shrink because I've learned that most stickers do pull back a bit on me after they've set completely. Also, can I say that I wish the skulls faced down toward my tips?! The world should being seeing my skulls, not me. :)
Overall, I really like these. They are super blingtastically sparkly and the skulls, while not being nicely defined or easily identified, are a very cute and edgy addition. Normally I get amazing wear on my stickers, but because I was a dolt and didn't top coat these, I had a major crazy chip near my one cuticle and several other chips on tips within about two or three days. So sad! I should have been able to get at least six days out of them (with top coat). Lesson learned!
