I have quite small hands and nails so I bought the XS size which still carried a good variety in the pack (10 different sizes, 24 nails total). I used the style 143 Fench Manicure - American Pink, this has the classic French tip and the nail has a mild pink tone but matches my real nail well. Due to the XS size the tip isn't too long, so although they don't look real (obvs!) they aren't ridiculously long and false looking.
The pack includes the nails, the glue and nail file so you can shape the nail and shorten it if desired. The nails have a tab on the end for easy application and are a doddle to apply. The nails fit comfortably on the finger and once on they feel secure.
So far I am really happy with these nails and pretty pleased to have saved £20+ by not going to a shop, plus I know my nails won't be as wrecked as they would be by acrylics! I will update this post about wear and tear once I know more!
