Homplus, one of the largest marketing chains in Korea, has recently started selling Bigbang goods!
"Items such as pencil cases, notebooks, card holder necklaces, filing folders, and shopping bags (etc...) with BIGBANG prints have been carefully selected into 30 different types, aiming for what a crowd aging from 10-20 years old might enjoy."
"The pencil cases are ranging from 6800~17800WON (approx. $6.50~$17.00 USD), gel pens 5800~11500 (approx. $5.50~$11.00 USD), notebooks/notepads 1200~6000 (approx. $1.25~$6.00 USD), card holder necklaces 25000 (approx. $24.00 USD), files/filing folders 1000~7500 (approx. $1.00~$7.10 USD), and shopping bags 1800~4500 (approx. $1.70~$4.50 USD)."
