It's approximately 21 cm tall, 13 cm wide, and 3 cm thick. I don't remember using it, but it's been stored in a closet for a long time, so I've listed it as "like new." In reality, it's in pristine condition, like new. It has many storage pockets, and it's very convenient for carrying valuables like your smartphone, wallet, passport, and tickets, especially when traveling abroad, such as during airport transfers. It's really handy, you know.
