Those press-on nails suit people who like to change nails frequently or who need to play musical instruments, cannot maintain long nails, and just wear press-on nails for special needs. If you wanna keep press-on a little longer time, just buff a little your nail surface before applying. if you wanna keep a much longer time, please use press-on nails glue. if you just wanna keep for a short time, jelly gel glue is good enough. when you remove press-on nails with jelly gel glue, just soak ur nails in warm water for 5 min , then it would be very easy to take it off.
