Press-on toenails can last anywhere from a few days to about two weeks, depending on factors like the quality of the nails, the adhesive used, and how well they are applied. Generally, they last:
A few days if they are exposed to water frequently or if the adhesive isn’t strong.
Up to two weeks if high-quality nails are used, a strong adhesive is applied, and they are kept dry and protected.
For the longest wear, avoid soaking your feet for extended periods and consider using a nail glue or adhesive tabs that are specifically designed for longer wear.
