About

On the nail side, clients can book gel manicures without builder gel or BioGel manicures with builder gel, with add-ons for nail art, matte or shimmer finishes, cat eye, ombre, blush, chrome and French designs. Gel-X and dual forms extensions and fills are offered in short, medium and long lengths. Dual forms are described by the business as producing an even arch and shape. Press-on nails are available with the client's own tips or with Rainbow Joli tips.

Blind Box Nail Art is a separate nail-art service on natural nails. It includes delicate prep, a hard gel overlay and art materials that the business values at $120 or more, for $100. The artist chooses the design, mostly in Korean or Japanese hand-painting styles. The service takes about two and a half hours. Nail removal and tips are not included in the Blind Box price, and removal is charged at the store's rate unless it is natural nail removal done by the business.

The lash menu runs from a lower lash full set to classic, 2D, 3D, 6D and 9D volume sets, with anime, fairy, foxy, wispy and hybrid styles starting at $108. The 2D Mermaid set uses YY-style designs. Lash fills are discounted from the original set price when booked within two, three or four weeks, provided enough of the lashes remain in place.

Pedicures come in three tiers. The basic pedicure covers nail shaping, cuticle care, buffing and regular polish. The Bloom and Rainbow Glow pedicures add a foot soak, scrub, callus and heel smoothing and a foot massage, and both include a free builder gel base with a solid gel color upgrade. The Rainbow Glow version adds a hydrating foot mask and a longer massage.

The business describes it as clean and hygienic and as a gentle procedure with minimal discomfort.

Services, add-ons and lash fill discounts are listed with clear prices, times and booking rules.
