This is very easy to apply! I was hesitant at first as well but this liner is fantastic! It might take a couple applications to get the hang of it, especially if this is your first time using this type of liner. It took me a few days to get use to it. I promise it's so worth it!
this is easy to use! i find it easier than liquid eyeliner and similar to the pencil kind. i never used it with eye shadow or anything. in my experience it definitely smudged less than a pencil kind, but it did smudge a little. an eyeshadow might help it.
