Just the right amount of abrasion to smooth out those ridges; don't over-do it, though! All in all, a great product and a great price AND free delivery, what more could you ask for x
This takes out the ridges in my nails and gives a nice smooth surface for perfect polish. Sometimes, if the ridges are extremely deep, it's not enough to file them down, need to fill them instead. But this buffer is perfectly fine for most.
Very good buffer, works also for natural nails
Love this tool don't hesitate to buy
