This is a FoodSaver brand vacuum sealer roll set. It includes two 28cm rolls and three 20cm rolls. I received these a while ago, but I didn't know how to use them, so I just put them away. I learned that a special machine is required, but I won't be using it, so I'm selling them. By the way, one of the cases is open in the fourth photo. I only opened it to check how to use it, so it hasn't been used. I've sealed the open case with masking tape, I apologize for that. #FoodSaver #FoodSaver #VacuumSealerRolls #KeepsFreshLonger #Set
