Toma 45 seconds top coat 13ml/0.45fl.oz. All top coats do the same thing: they protect the colour and dry the top coat. 45 seconds dries the topcoat in - yes, you've guessed it, 45 seconds. It has a high gloss and can be used with any polish. The great thing about this topcoat besides its drying power is the fact that you can get almost to the bottom of the bottle without it getting thick.
