Kodi Professional Monomer is liquid with which the acrylic powder becomes a finished nail. Thanks to a unique technology, the manicure hardens within a few minutes but does not completely lose its flexibility and plasticity (just like natural nails). The Monomer does not spoil the colour of acrylic or make it any less bright or sparkling. Kodi Professional Monomers are presented in two forms: transparent and purple. Transparent monomers are best used if you have coloured acrylic. Purple is ideal if you do a French manicure, and it is necessary to achieve an ultra-white colour that does not become yellow with time.
