JustNails Premium Pinch clamp for easy pinching of the nails. Through the pinching you achieve a much nicer C curve and much more stability in the nail. This makes the nail more resistant to breakage and you can model the nail accordingly thinner. In addition, trapezoid nails and very wide nails can be prevented. It is best to glue buffers or cut parts of a file into the pinch clamp so that it can lift perfectly on the nail when pinching. The easiest way is to use our self-adhesive file blades for the metal boards. You only have to cut them to size. They are thin and stick by themselves. Let the desired and pinchable gel (all fiberglass gels, also fiberglass cover gels and our Lux Gelee build-up gels) about 13-15 seconds in a UV/LED lamp harden and then take the nail out of the lamp. Clamp the pinch clip to the nail and squeeze it into the desired shape. Let the finger WITH the pinch clamp back into the lamp and cure the nail to the end.
