I'm a very anxious person and find myself biting my nails quite often. Last Sunday I purchased these nails and they lasted until this Saturday. Keep in mind I was doing house chores like washing dishes and cleaning up daily. I was amazed nonetheless They were so cute, a great fit, and very comfortable, they also kept me from going at my nails all week. I am going to repurchase these soon. They're a great affordable alternative to acrylic nails.
