No, very bad idea. Go buy eyeliner and use only that. There is no excuse not to. Brands such as wet n wild, essence, catrice, la girl, la color, nyc, jordana, klean color, city color, elf, j cat beauty, bronx colors, nabi cosmetics, etc are so cheap with pretty much all being under $5, many times on sale or buy one get one free so anyone can afford them. There is no reason to endanger your eyes and overall health while looking ridiculously horrible with pens and toxic things not meant to be makeup when safe quality make is so affordable and easy to find today.
