Roller for Stretching Facial Treatment Oil

I recently started using Argan oil on my face, and really like the results. It comes in a bottle with a dropper, which is fine, but makes for some waste. If my hands are dry, the oil kind of disappears before making it to my face! My solution was to buy a roller bottle on Ebay (I have also seen them on Amazon) and fill it with my Argan oil. Now, I just run the roller on clean face and then massage in with my fingers. The oil goes much further, and there is little chance of spilling.
