The shavers and trimmers I've bought have all come with a thin, eyedropper sized container of oil.They've all leaked and are easy to lose. Considering that one only adds a couple drops of oil to blades and trim heads on occasion, this generously sized bottle of oil should last a lifetime.The oil dispenses neatly from the container and is easy to control. Just twist the top to open and twist again to seal the deal.I use this oil on my two shavers and my hair and beard trimmers with no problems. Regular oiling keeps the appliances working well and the blades sharp.
