BSB slingshot elastic yellow
BSB (Burning Skull Band) yellow flat band exists a long time in Chinese market.The brand owner is famous in China with frame-less shooting. He had a nick name JIDILAOYAO 极地老妖(polar sag, i hope this is the correct translating).
The long time existence in the market is the best proof of its quality.
Personally i think he was the earliest slingshot influencer who had started to upload video to present his frameless shooting skill at least 8 years ago.
