I've used this about three times and then stored it at home. Size: Height: Approximately 17cm Width (top): Approximately 24cm Width (bottom): Approximately 18cm Depth: Approximately 7.5cm Shoulder strap is adjustable. Please note that there may be slight variations due to amateur measurements. It can still be used for a long time, but please understand that it is a used item, so there may be minor imperfections. Thank you.
