These are chemical lights (disposable glow sticks). I used them for a color-guessing quiz during a wedding reception's costume change, but I have some unused ones left over, so I'm offering them for sale. Blue: 2 Orange: 2 Green: 1 Purple: 3 As of August 2025, they light up without any issues. Please refer to the 4th image for how brightly they glow. They have very vibrant colors and were a big hit at the wedding. I'll also include the ribbon that was attached to the basket for the glow sticks as a bonus. (Please note that the basket is not included.) Individual sales are possible, but I will prioritize those who purchase them as a set. (If sold individually, they will be 60 yen per stick.) *Please only purchase if you understand that these are items managed by an amateur.* *Although none of them leaked when I used them, it is said that sometimes they can leak. I cannot take responsibility for this, so please understand.* Chemical lights Disposable glow sticks Costume change Wedding reception Party
