2. Sephora by OPI 3 in 1
Price: $14.00 at sephora.com
This is a definite must have for all of you ladies who, like me, hate having 5 different top coats, base coats, strengtheners and God knows what. I totally love 3 in 1 products because of their effectiveness and simplicity. This one, by OPI, is designed to give you all the benefits of a regular treatment for stronger nails, help your manicure and pedicure last longer and give them a glossy, resistant top coat.
