Yes, you can buy a BTS light stick at the concert venue because there are special shops at the concert where you can find many BTS things like light sticks, shirts, and posters, so you can go there before the concert starts and buy what you want. 💜
It is a good idea to go early because many fans want to buy light sticks, so sometimes they sell out quickly, and you might have to wait in a long line, but if you go early, you will have a better chance to get one. ⏰
When you buy a light stick at the concert, you can use it during the show, and it will light up with the music, so you can feel like you are part of the BTS family and enjoy the concert even more. 🎶
If you want to be sure you get a light stick, you can also check if you can buy it online before the concert, and then you can bring it with you, but it is okay if you want to buy it at the venue too. 📦
