I think the Nicole by OPI textures are similar to OPI's shatters, if not the same. I don't own all the OPI shatters so I'm not positive, but I think I read somewhere that they are.
Overall, the collection isn't anything new from OPI, except for the gold texture. If you don't own any of the shatters, you may want to pick some of these up. Steer clear of the white texture though.
I'm personally done with the whole shatter trend now that I own these. The only ones I may pick up are from China Glaze's metal crackle collection, since I prefer metallic crackles to creme ones. However, I don't feel I need them. They were pretty cool at first, but I actually don't reach for my shatters that often. I think the only thing that would excite me would be holographic shatters. Seriously, why not? When shatters first came out everyone was layering them over holos. Only it seems to cover up the holo, so I'd really like a holo shatter since we'd see more of the holo. I don't think it's going to happen though. :P
What are your thoughts on the whole shatter/crackle trend? Do you own any of the Nicole by OPI textures? Let me know in the comments! :)
