NOT another Rum Runner question

[cajunpeach]

I read (and did not save) a thread that discussed bringing alcohol onboard. One of the posts was about an alternate method using lids that went onto water bottles that made them look like they had not been opened. I've searched every verbage I can think of and can't find what I'm looking for. Does anyone know what they are called and where I can buy them?

TIA :D

Just returned April 23 from Carnival cruise. We used the rummer runners, placed them in 4 different bags and all made it to the room. No hassle!:)
