The eyeliner is very long lasting and doesn't smudge just like it claims! ❤️ I've worn this eyeliner for 11 hours and it still stayed on!! The Brush isn't flimsy like most eyeliner brushes nor too thick. The formula isn't really inky as well which makes it very easy to use, and suitable for beginners since the Brush is stabled and really suitable for daily wear like for school/work. I reaally love this eyeliner so much and will be purchasing the brown one too! 😍😍 (The selfie taken was after 11 hours of wearing the eyeliner :D)
