I wanted to love this pen, the idea is so awesome and handy. But alas, this thing was so bad for me. The concealer comes rushing out and then it leaked if I didn't leave it in an exact upright position. I will give it the benefit of the doubt and say maybe I am using it wrong.. but I am doubtful. I am glad to see it's worked for some many others but for me, I would not recommend or ever purchase this again. Originally posted on www.maccosmetics.co.uk
