This is an amenity pouch provided in Delta Airlines business class by TUMI. The contents have been discarded for hygiene reasons, so this listing is for the rectangular pouch only. It is made of ballistic nylon and is very sturdy. Besides using it as a small item case, its durability makes it suitable for storing golf balls, fishing tackle, camping gear, etc. Size: Approximately 11cm tall, 17cm wide, and 5cm deep. It has a surprising amount of storage capacity, easily fitting a smartphone, a bifold wallet, and a 10,000-20,000mAh lithium battery. Thank you.
