In a crisp white salon adorned with ebony silhouettes of floating leaves, Charming Nail & Spa's nail technicians hone handsome hands and feet with luxurious mani-pedi services. Cushy leather pedicure chairs cushion torsos as feet simmer in soothing warm water to prepare for a thorough paw polishing and to melt away remnants of Arctic tundra work commutes. Manicure mavens then remove rough calluses, refine cuticles, and buff toenails to a healthy glow before applying a layer of eye-catching lacquer. Digit adornments finish up with a thorough buffing, cuticle pushing, polish application, and a lecture on the dangers of rustling through purses.

For longer-lasting lacquer radiance, OPI gel manicures swathe the natural nail in durable, vibrant color that permanently sets beneath UV light within a matter of minutes. The gel polish leaves nails free of chips, smudges, and errant candy wrappers for weeks. Once ready for removal, the gel soaks off easily without damage to the nail bed in a single salon appointment.
