Mosaic UV Lac is a true gel-polish (unlike other gel polishes which are just very liquid soak-off color gels). It is applied in a thin layer, which is very flexible. Removable in just 5 minutes with a soak-off remover liquid — without the help of a nail file or buffer! To soak-off the UV Lac, use our special Mosaic UV Lac 5 minute remover. Cures in both standard UV lamp or LED UV.
