This is a very durable pre-formed nail nail. It has really good diversity of tone, and is very responsive. They're thicker and a bit more difficult to apply than our type 1-A and 2-A pre-formed nail. Has a natural appearance after application. All of our nails are customizable and fully adjustable.If our pre-formed nail is too wide, simply trim the side with some scissors to fit your natural nail plate, this only takes a couple of seconds. If your natural nail is a bit too wide for the pre-formed nail, make sure the short side is the right "pinky" side. Make sure the left border (thumb side) of your natural nail is in line with the left edge of the pre-formed nail.If the curve in the pre-formed nail is a bit too much, you can flatten it out a bit to match the curve of your natural nail by holding it between your thumb and index finger, and gradually increasing pressure to flatten the curve. You can also increase the curve by using our manicure stick and rolling it back and forth.
