Because it's my birthday. Aren't disposable bands this cute?! The price is a whopping 1,000 won!!! Wow~ I should buy more. It's a panacea for families with children. The only requirement was that it was expensive so that the cute siblings would like it! It was like 3,500 won per piece. If I had known the price, I wouldn't have bought it >.< I think it has a mold inside and the chocolate included is melted, squeezed, frozen, and then decorated.
