My overall experience with this eye pencil has been pretty good. I had some doubts about it early on because when I swatched the liner on my hand it did tug and pull some. I also had problems using it to line my upper lash line, because it tugged so much. I also notice that I had a hard time applying it after I had applied my eye shadow, it was like it did not want to glide at all across my lid with the eye shadow on there. However this eye pencil worked great for 'tightlining' my upper lash line, which is something that I have been doing a lot lately, and it worked great on the waterline. It really does have amazing staying power.
You can get the Sumita contrast eye pencil from Birchbox for $11.00. I could not find a website for Sumita where you buy products directly from them.
