I received this Butter London Nail Apothecary Treatment Set as a cute little gift earlier in the year. I'd have to say it's become one of my most-used nail products.
With formulas designed to strengthen, protect, repair and hydrate the nails, the set includes a cuticle oil, cuticle eliminator, nail strengthener, basecoat, shiny topcoat and matte topcoat. The last one mentioned is quite wonderful for those shiny nail polishes you no longer get use out of to achieve a simple, muted effect. The cuticle oil adds long-lasting moisture to the surroundings of the nails and the basecoat is an essential to prevent nails from staining.
If you're serious about stepping up in the nail game, this kit works wonders.
