amazing applicator. i only bought this to apply the product easier. i also love the rose quartz roller ball, as opposed to a plastic one. other than that, it's just organic castor oil. what i do love is it's refillable. i got a deal on it with coupons. i also wish the cap wasn't cheap plastic. it can crack easily. but if u want the applicator to refill, then get yourself one. one more thing, is it comes with an expiry date but castor oil doesn't expire or have a limited shelf life. Just a marketing tactic.
