I really have tried everything from nail salon, shellac, natural paint in Studio..will no acrylic or similar. Since I found Microcell at amazon, I have healthy, natural, not splintering or tearing nails, have applied to Repair paint and top coat as Kurzkur. Lately, I must nail filing :-) just great Only this paint is color-wise not so shiny, rather dull ... the color table is still too low.
