As with all OPI products, this shatter is a long-lasting, colourful, nail polish. You apply it over a colour of choice and as it dries, the polish will shrink and split apart, creating a 'shatter' effect that reveals your nail colour underneath.
The polish itself is quite thick which makes it somewhat difficult to apply compared to regular nail polish. This also makes it prone to drying out, so you have to use up the bottle within a few months or it will dry up and become unusable.
You also must apply the shatter over your entire nail quickly as it dries incredibly fast for the shatter to work, and applying any more than one coat will ruin the effect.
Although I personally don't like the shatter effect enough to use this product again, it is well formulated and exciting, and does exactly what it says it will.
This shatter effect is very satisfying to watch and really does what it claims! Please note that if you dont apply a solid-enough coat underneath, the shatter "drags" the below colour and reveals your nail colour underneath! So do your prep before hand. I have the black and silver shatter and get lots of compliments when I wear them!
Tips: The shatter effects looks best on medium to long length nails. Always always finish with a top coat or two.
