They work great in my Panasonic MC-CG917 container vacuum. At first glance they appear to be very different in size from the original manufacturer's bags, but if you simply fold the sides over to create folds like the original MC-V295H bags, they are almost the same size and shape. In other words, take the folded sides and slide them towards the center of the bag to form jagged folds like the original bags. Hope that makes sense!
