Hi, i know this isn't really related to music, but for those who have been to many concerts like Lovelive and AFA and stuff, would have seen these Light sticks that can change colour incredibly fast, I've seen them in concert dvds being turned into whitish gray and light blue and stuff and not just fixed to the normal Blue. So if anyone has seen or know where i might be able to find this in SG or online stores that does deliveries to singapore quickly, then please tell me!
