Plane Pal Airplane Air Cushion This is a pump-operated model, not an electric pump type. *Please note that there is a new automatic type currently available, but this is the pump type, so please be careful not to mistake them. I purchased this new while living in Germany and used it twice for round trips in Europe. I inflated it again for the photos and confirmed that there are no air leaks. There are some light-colored stains, but they are not noticeable and it is generally clean. It takes some time to inflate because it's large. The construction is sturdy enough to withstand up to 90 kg. There is no paper instruction manual. Please purchase only if you understand that this is a used item, stored by a non-professional (no pets, non-smoking environment). The product will be deflated, protected from water damage, and then shipped via either Rakuraku Mercari or Yu-Yu Mercari, depending on the packaging. Both are anonymous shipping methods. Please feel free to contact me if you have any questions about this item. Thank you. Please check the regulations of each airline regarding its use. It may not be usable if you are in an aisle seat. It can also be used in a car. It makes your legs comfortable during long-distance travel. I haven't used the famous Fly Tot, but the shape may be similar. FLY TOT is also high-end, but this also cost over 10,000 yen. Perfect for those who want to get it at a lower price. My family used this and the Stokke JetKids for our two children. Thanks to this, our children slept well on long-haul flights without fussing.
