Hi Frances, we would’ve removed everything and redo the nails if we had know that you didn’t like the work the second time around. Tai mentioned that he asked if you were happy with the fix and you were okay with it. Sorry to hear you weren’t happy with the result. If considered stopping by again, we’re happy to offer a discount for your next visit to compensate for the inconvenience.

Son amables pero las uñas de mi hija no duraron nada apenas tienen 5 días y una ya se despinto x completo ...otra cosa es que dejan parte de las uñas de los lados sin pintar. Deberían poner atención a esos detalles . La atención al cliente es muy buena..
