I have opened it, but I have never used it. Although it is unused, I have opened the package, so I've listed it as "Like New." It's the type that inflates with air by pressing the round pump on the left side, so you can use it without putting your mouth on it, making it hygienic. Please refrain from purchasing if you are sensitive to items stored at home. #NeckPillow #NeckPillow #TravelGoods #TravelSupplies
