EzFlow, Nfu.Oh, Young Nails, NSI, loads of companies have premixed coloured and glitter acrylic powders. Nfu.oh having the most extensive range.
The only downside to a full colour acrylic nail is if the client wants a change of colour at her rebalance appointment, then you need to soak off and start again, or if you have applied a thin layer of clear before the colour file all the colour off hard work :irked:
These powders are great for glitter or coloured tips and designs, and of course 3d work, but I do think with the advent of gel polishes then they are best used if a client wants full colour nails.
