I purchased this about three years ago and used it when riding my bicycle. It has been home-cleaned. It has two zippers, and one has an inner pocket. There are no noticeable scratches or stains, but please understand that it has been stored by a private individual. [Size] *Please forgive any errors. Pouch section: Approximately 10 x 20 x 2.5 cm The following is an excerpt from the product description on the website: [Adjustable]: The Guzack sports arm pouch is ergonomically designed with dual adjustable Velcro, and the hook belt uses elastic stretch material to apply to both arms and wrists. The hook belt size can be adjusted from 14cm to 40cm, suitable for a wide range of arm sizes. [Excellent breathability]: The smartphone arm pouch uses elastic Lycra material that is gentle on the skin and has excellent breathability, protecting the smartphone body from sweat, sudden rain, scratches, and impacts. The back of the marathon pouch is designed with a waterproof and penetration-proof material in a honeycomb pattern, and the designed back is wider and has better breathability, effectively reducing the discomfort when the strap is tightened on the arm. [Excellent storage capacity]: This large-capacity mobile pouch has multiple pockets, and can store all small items. In addition to smartphones, you can store keys, earphones, IC cards, and other daily necessities such as cigarettes. [Night reflection and emergency contact card included]: The Guzack running pouch uses a night-reflective material, so you can run with peace of mind even in dim conditions. An emergency contact card is attached to the transparent pocket on the front, and you can write the contact information of the emergency contact person on the card to protect your safety in case of an emergency. You can also peel off the card and put other products such as photos in the transparent window. [Compatible models] The running and work mobile storage pouch is compatible with smartphones up to 6.8 inches. *We cannot offer a discount. MPM6J
