I originally bought these drip tips for the three longer drip tips. Yes I am one of the weirdos who really get off on a nice long tip for my mouth to lunging. However was pleasantly surprised by just how comfortable some of these drip tips are. The tulip shaped tip in particular whilst not the most ascetically pleasing, is one of the nicest feeling I have used. Though not every drip tip fit completely flush with all my tanks. Still a great purchase.
