It's a very sticky nail gel, it doesn't run to the sides, but it's self-leveling. Plastic, perfectly C-shaped, forms in 15 seconds. The device is single-phase and can therefore be used both as a modelling tool and as a base and top layer. Ensure good adhesion of the natural nail plate to the modelling device. It is ideal for nail augmentation, correction and natural nail plate strengthening. It goes great with all Profnail gels.
