I have to be honest and say right off that I usually don't buy the Sephora branded products because they offer so many upscale products in their store. I decided to try this liner because it was cheap and my go-to liner (Bobbi Brown) was a pain to constantly carry an angled brush and cleaner around with me at all times. I was shocked when I tried this! The packaging is shaped perfectly to draw great lines and the liner lasts a long time on my oily lids. 24 hours is certainly not true, but I can attend class for 8+ hours and still have great looking liner. When it does start to come off, it just gets spotty instead of becoming a smeared mess. I hope that Sephora keeps this in stock for a while.
