Proper nail preparation before applying press-on nails is the key. Make sure to file/cut your nails short, push your cuticles back, and buff the nail bed with buffer. Clean thoroughly with alcohol wipes to make sure there's no dust/oil on your natural nail bed. Once you have done these prepping steps, 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 dried.

1. Nail adhesive tabs are easy to apply and perfect if you don’t want to keep your nails on for a long time. No no damage to natural nail beds. You can use press-on again after you take them off. They are easy and fast to remove. However, they don’t last longer than two days.
Some adhesive can make the nail look raised or bulky, and less natural. Some activities may cause the nails to fall off, such as typing.

2. Press-on nail glue is actually a pretty vague term since there are a lot of different kinds. Usually, glues will last a lot longer than adhesive tabs, sometimes even for 2-3 weeks with a bit of extra care. However, the nail set cannot be reused again, so if you planning to reuse this product, do not use nail glue.
