I swear by this!! I've used this for years!! No need to fiddle with sharpening and lighting your eyeliners on fire to get going, just pop it open, twist, and apply! And honestly, if you dont take it off it will still be there the next day. Waterproof indeed!!

Terrible Product.It is smooth but not dark enough as I used black one.Its tip broke first time i open the lid and it keeps happening everyday .Price was less but quality needs to improve.
