These nails are awesome!!!! I can't have my nails done for work so when I have a week or so off at a time, I love having my nails done, and especially longer than usual. These press-ons are so great! The glue was a little tricky the first time I used them and I got it all over my fingers but the second time it was much more manageable. They lasted the full 9 days I wanted them on and didn't seem ready to budge so I think they could last longer as well!I found it easiest to gently file down the top of my nails to roughen them up and then use the glue bottle to spread a thin layer over the top of my natural nail. Then, I pressed on the nail that fits best and held it there for about 30 seconds. Once it dried, I filed them down to the length I want (some nails are the perfect length already and some are SO long) and then painted them!They are a little difficult to take off but nothing crazy. I took off the polish, filed the top layer of the nail a bit, and then soaked them in nail polish remover. They slowly peel off at the edges and you can get under them and peel them. They, unfortunately, do damage the top of your nail a bit but I didn't notice any lasting changes past 2-3 days after.I highly recommend these nails if you are looking for some quick and easy length.
