The set contains 100 pcs of nail templates for concave nail bed. They come with a preset cutout for this type of nail bed. The template is made of paper doubled with aluminum, to give extra hardness to the template and for easier modeling during its assembly. I thought of the template in a hexagonal shape for a more precise gluing and for a more correct position of the hand in the lamp to avoid product leaks that occurred when the hand was slightly tilted due to the "ears".
