I used this once and have been storing it at home. Instructions are not included as I have quoted images from the website. You can inflate it by simply pressing the pump at the neck with your finger, making it very convenient for travel or when you're out and about. After use, you can deflate it and store it compactly in the included pouch, which is convenient for travel. The protrusions on the left and right sides firmly support the head, supporting the proper posture of the neck. The cover is made of soft micro-velvet fabric and is removable and washable. External dimensions: Width 305 x Height 290 x Thickness 115 [mm] Weight: Approximately 242g Storage pouch: Diameter 115 x Height 150 [mm] Thank you for looking. #NeckPillow #Pillow #Travel #Airplane #HighwayBus
