This is a tool for vacuum-sealing food. It can be reused after washing. I purchased it last year, but it has been kept unopened and unused. I only turned it on once to check the operation. I believe there are no issues with its functionality. The box and instruction manual are not included, but all the contents are present. (Vacuum pump unit x 1, Charging USB cable x 1, Vacuum plastic containers M and L x 1 each, Vacuum storage bags S and M x 2 each) Thank you. #Zwilling #KitchenTools #StorageContainers #VacuumPack
