I don't like metal drip tips at all because of my sensitive teeth, so every time I order my fav strawberry shortcake juice from here, I usually add one or two of these plastic drip tips. They fit my istick picos and my Vaporesso Attitudes. I have about every color in multiples. They are easy to clean (with a cloth or in a hot water bath) and there is no disintegration. I am using five of them in five of my tanks right now. I will keep ordering these to ensure I always have enough!
Nice looking and good height delrins, however , had to rework every drip tip, sand down oring groove, too fat to fit Kanger sub ohm minis and older pro tank 2. The slow delivery did not help.
