These I was super excited for. I'm a sucker for blue polish in general and then the shatter just pushed it over the top for me.
The formula for all of these was perfect. I was disappointed with Silver Shatter and so the shimmer in the Turquoise and Blue shatters made me nervous, but it really didn't make a difference. It was the same with the shimmery purple from the China Glaze crackles - some people were really disappointed with them but mine worked fine.
Turquoise Shatter is a very pretty, tropical water sort of shimmery turquoise.
Navy Shatter is a dark, almost jelly navy color. Similar to Nars' Midnight Express polish.
Blue Shatter is a shimmery royal blue.
All three are pigmented and need a top coat in order to really get the full potential of color.
They're between $8 and $9 and can be found wherever OPI is sold.
