As with all OPI nail varnishes the shatter top coats are very high quality. I really like the black one to go over metallic nail varnishes. They are super easy to use just a quick stroke of this over a base coat colour of your choice (doesn't have to be OPI colour, completely up to you) then as it drys within seconds the nail varnish separates leaving behind different shapes of colour and the base coat visible underneath. A lot less messy and fiddly than nail art pens or stencils. It's really quick and easy to apply and dries really fast leaving behind a nice pattern than doesn't chip, I like to seal it in place with a glossy top coat just to add shine. These OPI shatter top coat nail varnishes come in a range of different colours too and they are a lovely present, young girls love them and they still work very well on small nails. It's really easy to remove, just with regular nail varnish remover. The nail varnish size is large too so you get tons of product meaning it will last you a long time as you only need a thin quick layer over the base coat.
