I have these in five different colors and love them. In addition to the obvious advantage of adding fine-point bling wherever you want it, they are also good for filling in awkward spaces. For example, if a large gem does not adequately cover the paint and there is a bit of skin peeping through, you can use this as a "patch" by making an attractive design around the gem. They also spread well, so you can either use them like a pen or like a paint.
I feel this adds a compliment to any design. Makes a delicate touch as well
You can never go wrong with liquid bling! It's easy to use and has good longevity to it. I specifically went with gold, so that when I forget the horn on my unicorn cheek art, I can pull out some liquid bling and really add that WOW! factor.
