Obviously the rack could hold more than 24 if they were all the canister type and fewer if they were larger containers. #3: Gloryfire: When volume is off, they have great decibel reduction, but when sound is on, they are not that good ? you can hear the start of a blast before dampening kicks in and to my ears at least, they don?t seem to dampen as much. It?s so stinking cute I almost can?t stand it! I hate how the other brands have flimsy "sticks" (for lack of better description) that buckle, or the cotton comes off the end while in use - or is just missing from the start - etc. I was a little concerned when I first ordered them, and seeing how so many people stated to go a size up AFTER I ordered them. really need almost double that amount. So the seller must not have control over their part numbers. A well deserved 5 stars from me. Very well built and should last for a very long time. Worked just as good as top brand
