I only use what I consider to be the best products on the market. I use O.P.I. for all regular manicures and pedicures assuring quality and safety as the company uses products that are 3-Free (No Formaldehyde, Toluene or DBP). All of our manicure and pedicure products are from the 'Kaeso' range, they contain no glycol acids, parabens and no mineral oils. They are vegan friendly, and they smell divine!
