Proper nail preparation before applying press-on nails is key! Make sure to file/cut your nails short, push your cuticles back and buff the nail bed with buffer. Clean throughly with alcohol wipes to make sure there's no dust/oil on your natural nail bed. Once you have prepped, apply your press-on nails and avoid water contact for at least 2-3 hours. It's important to avoid water contact until the glue is completely dry.
