“Punch the !ighting”, printed on this large poster image is pretty irrelevant. It might looks like He is punching that sand bag, but that piece of bag isn’t really a punch bag according to the concept designer, Jun Bum Park and Kim Jin Sook.
The real trigger on this LED punching bag is the punch to bend the bag once to activated the light. Absolutely, you CAN’T use it as your de-stress object and punch it like furiously! You’ll absolutely break the circuit and end its life!
“Slow = Stress + Low”, WTF?!
