If I look upwards they almost hit my eyebrows but since my own, natural eyelashes are apparently 11 mm., they are only 1 mm. longer. The thickness, curve, and color are definitely what makes them this obvious. I'm not into looking 100% natural and makeup-free so I don't mind the dramatic look at all, it is exactly what I wanted! I got them done at WINKCopenhagen which I highly recommend; the process was extremely pleasant and I even got to sneak in a little nap, since you lay down.
I really think extensions are a great way to save time on your lashes, albeit a little expensive. I'm excited to see if I at some point start to think they weren't worth the money.
