Cheap alternatives to "cigar" beads?

Shilala,

I have some Heartfelt beads in my wineador right now but I don't think there are enough. I open it daily at least once per day. I kind of want to keep my humidifcation devices uniform. Since I'm opening it daily do you think using your beads or more of Heartfelts will be better. What do your beads even look like? I haven't found them anywhere.
