This is an amenity kit from ANA's Hawaii flights, the Flying Honu, exclusively for Premium Economy. It's made of Tyvek, a waterproof and durable material from DuPont. Inside the pouch are an eco-bag and paper napkins. I obtained this in early October. Pouch: Approximately 18 cm x 13 cm Eco-bag: Approximately 32 cm x 29 cm
