First off, IF you have enquires about the string, please read this video Description. The string itself doesnt glow, its the UV light then made it glow. The string is a duncan polyester string. I bought them from Spinworkx Shop.
A one min freestyle with Yoyofactory's Protostar, one throw and its stock!
Used blacklight in my dim room, the effect is awesome! (well, at least to me)
This video ISNT sped up, think about it, IF its sped up, would it be a 1minute plus long combo with a throw? Thats harder.
