Using Vaseline for a neat manicure is a good idea, but you can't really see it. If you use Elmer's glue you can see it much better when you are finished painting your nails. You can rub it off if you do accidentally get it on your nails. Apply the glue with a brush and then just peel it away and it will take those corners and edges with it, leaving you with the perfect manicure. Hope this tip helped you!xoxosummeratparis
