WOW! I remember then. am going to ask the DR. for one. my DR. is also a deer hunter.Next time you are in your doctor's office, look for the otoscope (lighted device that looks into your ears and nose.) As for one of each of the three size disposable end pieces. I have never been charged for one. The are small enough to go into the smallest primer horn to the largest horn I own. To pour faster, place a small funnel inside the end piece. Works like a charm.
