I like this kajal because it's herbal and keeps the eyes moist. I use contact lenses regularly, and I have no issues using this kajal along with them. Also, this really helps my dry eyes problem.
I believe this kajal is more suited to medical use, that is for soothing the eyes, than for cosmetic use. As a beauty product, it smudges if used in good quantity, and simply vanishes within minutes if used minimally. In any case, it is meant to be used within the eyeline, and not outside of it.
I am yet to test the claims of eyelash growth because of castor oil. I will update that once I've completed using at least one piece of kajal. Till then, I certainly recommend it to those looking for a soothing kajal and want hygienic, hassle free application.
