I purchased a gowell neck pillow that can be stored compactly at a travel goods specialty store in Yurakucho. I used it several times on overnight buses. There are no visible stains or marks. It fits snugly and uses authentic low-resilience urethane. It's light and compact, so it's easy to use. Photo ① → It has a loop that can be hooked onto a backpack or suitcase.
