I am looking into purchasing a new vacuum sealer for my cakes, etc. I use to own a Seal-a-Meal and loved it. Was wondering if there is a brand out there that carry bags large enough to hold a 4" tall layer. I know some have reusable bags and would love this option, but again, not sure if they sell reusable or non-reusable bags that are large enough. Any and all suggestions are appreciated. TIA!
