The fake nails you get from Daison, London Drugs etc are just piece of plastic glued to your nails. They look VERY fake.
Don't use glue. They hurt your nails and when you try to remove those fake nails, you can remove some of your REAL nails as well!!!
To get gel/acrylic nails, go for a salon. I heard some people does ur nails on an oncall basis at home. They charge lower cost cuz they dun hv to pay rent.
