*I received these free for testing purposes, but all opinions are my own* The imPRESS Press on manicure in Harlem Shake is a one-step gel nail. It contains 30 nails in various sizes and has accent nails. The accent nail is a colourful floral print. These nails are great for spring and summer. I love how fast you can get your nails ready with these press on nails. The nail has a dual layer adhesive that attaches the nail to your real nail. I've been wearing mine for 5 days so far and they are holding up great even after hand washing dishes. These are safe on natural nails. I would recommend these.
