This is a must have if you’re doing your own nails at home. Before I had these bits, it took forever to even out my dip powder on my nails and to take down thickness. This does the job quickly. DO NOT USE THIS NAIL BIT ON YOUR NATURAL NAILS. this nail bit is for acrylic or dip.
Great value purchase. I bought this bit hoping it would help me eliminate having to file and shape my rubber base gel with hand files to give it a refined finish. I am extremely glad that I took a chance on it. I absolutely love this bit and several other bits from this brand. It definitely helps me achieve the desired finish on my work as I practice in beauty school and cuts down the time I take. I will continue to repurchase.
It's so much better than any generic round ball bit you could get, but it still has some trouble with cuticle flakes sometimes. I do wish it was a bit courser, as I think that would help. It preforms differently depending on the speed, low speed is good for cleaning the cuticles, and at higher speeds it can help shape the cuticle area on a nail enhancement. Also very good for grabbing stray pieces of gel or acrylic that made its way outside of the nail.
Makes back-fills a breeze! highly recommend! I love using this bit for pink and white back fills, it makes it so easy to make an arch And a deep curve for coffin shape nail. It's a great tool to save time!
