Wet n Wild Megalast Salon Nail Color. 5-day, chip-resistant nail polish formulas are just so darn great, they deliver a professional look that is far easier to get. Formaldehyde, toluene, and phthalate free! Our ManiCurve™ Pro Brush! It’s absolutely incredible! The rod is flat so the liquid drains down to the bristles equally, and the rounded bristles hug your nail curves perfectly!
