i originally trained with opi in manicure many moons ago, so use their products and polishes - however im started to put together a collection of polishes from various other companies and would eventually like to offer shellac also .. as a make up artist this its pretty much the norm to mix and match different cosmetic brands but do you think it looks a tad messy to do an opi manicure or pedicure , then use china glaze or cnd polishes?
