Replying to @mkingston93 A video explaining how to use the rebalance & undernail cleaner 🖤 we hope this helps The difference is in the size and grit. The Nicole is best for using around the cuticle area to refine product and is a medium grit. While the rebalance bit is larger, coarse grit and used to reshape hooked nails or clean the underside of an extension 🖤 #katiebarnes #katiebarnestoolrange #efile #fyp #nailtech
