Thank you for viewing. Please read the product description, even though it may be a bother m(_ _)m This is a non-sale item, a pouch from the Sumo Wrestling Fan Club. Height: 21cm Width: 13.5cm Depth: Approximately 1cm, but it should be able to hold a smartphone, wallet, handkerchief, etc. The length of the shoulder strap is not measured because it is bundled with tape. Thank you.
