Removal: I was worried I would not be able to remove the nails as needed, but as for the convenience of 'popping' them off I'd give this a 7/10. I would prefer a remover or tool so I could cleanly take off the nails as needed because 'popping' them off takes a lot of edge lifting and prying. My nails did grow out faster than the nail glue was 'ready' to let me pop off the nail but after some work prying off the corners removing the nail was possible.
Application: Super easy! Nail glue is always a mess but this is very straight forward and doesn't take long, especially if you have help! I glue the nail as well as my natural nail and I've never had one come off without me trying to remove it. I work with animals and these have definitely passed the durability test!
Length: the 'short' length was still pretty long for me so I did trim them with clippers after applying. Really attractive look though but I'd call the length more medium than short!
Reusability: Yes! Very reusable, no chipping or cracking even after forcing them off at times.
