This well-made little wonder easily fits everything I want access to in-flight in one place.  I just took a flight with it and it easily held a pen, lip balm, gum, headphones, earplugs, word seek puzzles, my iPad Mini, and more with room to spare.  There are also 2 slip pockets inside the smallest zip pocket, perfect for holding an ID and credit card.  Very happy with this purchase - now I won't be losing odds & ends into the seat pocket black hole!
