This product was not very effective. It chipped very easily and it did not glide on easily onto the nails. This product is meant to allow water and oxygen to pass through it, allowing your nails to retain its good condition while they are painted. I liked the packaging as it comes in a nice big bottle, which is a good size to pop into your handbag for touch-ups. However, the consistency of the polish is very watery. You have to build up the colour by applying several coats, which is not what you want from a polish.
