I used their discount code from their IG page and they were super cheap! If you are interested in buying them then I would definitely recommend getting a code from IG.
The nails are re-usable and last for a while. Every set comes with enough nails that you can mix-and match and use a second time around. Also, included is glue.
The sets that I bought were all in the "Stiletto" design (I love this shape and they make your fingers look so long!). I bought Samantha, Nakey and Cris-Cross and the quality is very good. I did have to file them on the sides so they could fit my nail bed properly and I may file down some of the nails as they were too long for me and I could barely do anything all day.
The one complaint I have, is when I removed the nails the glue was still stuck on my own nail and on the press on nails. I used nail polish remover and hot water but the glue would not come off. I'm still trying to figure out how to remove the glue and if you have any tips, I would greatly appreciate them!
Just a tip I would like to add, is to put the glue towards the base of your nail as opposed to covering your entire nail with glue. Since, your nail bed is much stronger you can just flick off the press-on nail after soaking your nails. This way you won't rip your real nail off at the tip ...I did this and my nail broke in half which was not fun at all!
P.S. I'm wearing Samantha in my picture.
