I have some considerable experience and expertise with this exact issue. I can tell you that I often carry
over 120 of the bracelet style glow sticks in my carry on. I put them in cardboard tooth brush boxes left over from various hotel stays. These support them rigidly so they do not break and each tooth brush box holds about 20-25 of them. Then I distribute the tooth brush boxes throughout my carry-on so as they are not concentrated all in one place. I have passed through security at SAN, DEN, LAX, NRT, ICN, TPE, and CAN numerous times this way and it has never triggered an alarm or caused any question even when very diligent screeners were manning (or womaning) the x-ray screens. I have grasp brief glimpses of the x-ray screen and could not identify anything unusual looking. I assume they would be subject to confiscation if they were discovered but there has never been an issue. What I do with all these thousands of contraband glow sticks is highly classified.
