I bought some Clero's that have a rubber protective cap on top. I just cut the tops off the cap and carry a couple around incase someone wants to try my vape. I just stick it ontop the driptip and when their finished I remove, put away and wash the sleeve at home. My wife has some friends at work who vape but are scared to online shop and get their same ol same ol juice from a local place. I like to show them that there is much better variety out there and it tastes darn GREAT and I get no cooties from them using my tip.
