The nib at the top makes for easy application to the cuticles without it being to messy and getting all over my fingers. When it says instant, it means instant! By the time I had finished putting it on all of my fingers the first finger's cuticles were ready to be pushed back. The whole process took less than 10 minutes, namely due to my inexperience, but I was really impressed by how much it affected how my nails looked afterwards.
It's such a great and inexpensive product, which I think is slowly being rolled out to Boots stores so it will soon be easy to find- although, I did buy it on Amazon for only £2.99!
