This is a Hello Kitty Tmoney card that was sold in 2011. Due to the Sanrio boom, it's become popular on Korean second-hand sites. (The product number on the back has been hidden for safety.) I've used it a few times, and the keychain part was previously repaired and replaced with a new one. It has a balance of 3750 won remaining. I've kept it stored in a dark place, so the condition is quite good. The price is based on the prices on Korean websites, but I'm open to a small discount. You can purchase it immediately.
