coming from a licensed nail tech....its safe. the lack of cleanliness from SOME salons is what's not safe. so go to a reputable salon...have the pedi chair cleaned in front of you beforehand, ask for ID and license. and definitely ask for a NEW file and buffer. if your tools aren't brought over in a sterile pack...do not proceed! ! if they give u attitude about asking for ID and license, DO NoT proceed. trust me.
