I have :
Base coat (002)
Polish drier (mavadry)
top coat (colourfix)
They are brilliant products and the polish drier and top coat work wonders!
All together they really do increase the longevity of my polish!
Check out the Mavala website for stockist, but I think these products are widely available at Debenham's, but do check the website to be sure!
Lots of love
