I have a liquid sand polish in a dark, navy blue colour. It is definitely something to get used to, that's for sure!
I found it felt a little weird. It just wasn't something I was used to - I am used to a smooth gel or matte finish; this is harsh and feels like sand. It is a little strange!
On the plus side it does last a long time without chipping. On the bad side, it is a right pain to remove. You really have to soak your nails on a pad soaked in remover and really hope for the best. It is definitely not a quick removal. So for this reason, I am on the fence.
This stuff will not leave your nails, which is a blessing and a curse.
The bottle is like the standard OPI bottle, but with a textured handle. The lacquer applies really well, and it's easy to put on, doesn't require a very steady hand.
When dried, the polish is textured like sand (go figure), which is nice for a change than the normal glossy finish.
Also, if you're the type of person who likes to just leave your polish on for ages - you're in luck! This still will not go away. But good luck when you want to take it off! You'll need a lot of remover and a lot of cotton balls.
