This was used by an elementary school child, but it was purchased at a general store, so it's a size that adults can also use. The bear plushie was attached to the backpack with a ball chain, but the ball chain is missing, so I attached it as is. Approximately: Height: 42 cm Width: 25 cm Depth: 11 cm It's clean as it's only been used a few times, but please understand that it is a used item.
