I used the Zwilling Fresh & Save system for a few months; here’s what I found. How the Fresh & Save worksThere are two different Fresh & Save starter sets: one comes with glass containers and the other hard plastic. Each set includes one medium (900 milliliter) and one large (2 liter) vacuum storage container, two small and two medium reusable plastic vacuum bags, and a rechargeable handheld vacuum sealer. Zwilling also sells additional storage containers and vacuum bags in various sizesI tested both the lightweight plastic and thick borosilicate glass vacuum storage containers. Unlike many standard vacuum sealing bags that rely on vacuum sealers that suck air out of the top opening, the Zwilling system is fitted with a circular vacuum port.
