COMMIT PRIMER: Are you ready to Commit? Even though Luminary Multi-Flex gel has amazing adhesion properties, there are still reasons to this primer. Every client is different, and some require more insurance that their gel stays where you put it!For a soak-off gel manicure, apply it to the free edge, capping the nail.For an overlay or other enhancement application that you will be backfilling, apply 2 coats (letting each layer dry completely) of Commit before gel application. ATTENTION: Due to high propensity to evaporate, this flammable product is very hard to ship, especially in warm or hot weather! Your bottle may arrive "half-full", but this is just physics - and there is nothing we can do to remedy it! Comes in 2 sizes: 15ml Bottle with brush and 8oz (236ml) backbar refill bottle.
