Many years ago when I did my acrylic course I trained in NSI, its been many years since ive used them but now im wanting to change systems Im torn between two. One of which being nsi attraction. The kit on their website looks amazing value! It comes with 7 different powders.. Sheer Pink 40gm, Radiant White 40gm, Radiant Pink 14gm, Totally Clear 40gm, Extreme Pink 7gm, Purely Pink Masque 7gm, Winning White 7gm. Obviously some of these colours are self explanatory and ive seen some being used in online videos but can someone tell me the difference between sheer radiant and extreme pink and when you would use each and the same for radiant and winning white? Thanks
