Vacuum-packing keeps food fresh, but most consumer packers are large and cumbersome, and each sealing requires a new bag. Instead of closing the whole end, the Frisper—about the size of a portable CD player—punches a tiny hole in the bag to draw out air and seals the puncture with heat. This allows the Vac-Snap bags to retain a zip-style reclosable top, so you don’t have to cut them open. Instead, you can vacuum-seal them multiple times to store daily-use food like coffee beans. $100; oliso.com
