I have very stubborn cuticles that stick like cement on my nail bed making it almost impossible to push back, especially in the corners. Additionally my sidewalls grow fast and stick making a nightmare for putting on Hard Gel nails and causing lifting. Normally I buy Sally Hansen Cuticle Remover (blue bottle) which is a miracle in a bottle. I still spend an exorbitant amount of time pushing back/removing my cuticles despite owning every cuticle care tool.Out of curiosity I perused thru Amazon for eFile bits specifically for cuticles and found this. Considering the grit on it is different than anything I’ve tried I figured what the heck. I just tried it first dry and then with some cuticle oil and WHOA‼️ Look at how much cuticle I removed considering I just filled my nails yesterday and thought they were as far back as they could go. In the photos I drew in yellow the starting point so you can more easily see where to look in the other photo.❤️ this and am going to buy a couple more as back up in case this one gets lost or bent. Miracle‼️‼️ I probably won’t need to buy the Sally Hansen anymore but that stuff does work miracles, may try in conjunction with this bit. AND using my eFile on low speed 4 RPM there was no heat ? no pain no bleeding ? and it seemed to melt thru the cuticle especially so after I added some cuticle oil and let it soak in for a minute. Worked just as well in Forward as in Reverse ?Super gentle for the corners. Love itGreat for cleaning cuticle, really small so you can really get close without damaging the cuticle itself.I love to use this for prepping nails. It is so soft on the nails and works nicelyArrived on time, works very well. I am pleased with the bit.Love it! Works well on natural nails, pretty much exclusively. If you use it over gel or acrylics, it gets stuck and will need to be brushed off with a a firm manicure brush. This will replace nearly any diamond bit used for prepping except for maybe the thinnest needle bits meant for cleaning up the sidewalls.My prep for hard gel includes using this bit, as well as a fine sanding band against the natural nails and skin. I clip off any excess dead skin with a cuticle nipper.A bonus? This can be used right over the skin! Sidewalls, etc. just adjust the pressure used depending on how sensitive the skin is. Don’t press very hard over the eponychium, but it’s great for removing thick dead skin. It’s much more suitable for sensitive areas than an arbor band in my experience but maybe my fines are not as fine as others.? recomendada fue una elección genial al comprarla no te arrepentirás de pedirla!It gets most of my cuticles despite how tough they areAwesome bits! I use them for cleaning my cuticles before applying acrylic, has definitely helped with lifting issues!I love these. They came as described and get my job done tooÇa a pris quelques semaines avant que la commande soit arrivée mais sinon bon produit je recommandeI honeslty think i could have found better bits but these are okFaire votres ongles à la maison sans depenser beaucoup d'argent et temps
