This is a Ziplock manual vacuum sealer which comes with three bags, and the page also displays the refill bags, that are also fairly cheap. For ya'll that're actually IN 713, the store on Dunvale supposedly has these in stock. They cost about $4.69 give or take a dollar, and they work fabulously! If you have a LOT of hops to vacuum up, you should invest in some of the gallon bags, they'll be sold directly next to the "starter kit" and cost about the same as the kit. You get 8 gallon bags for $3.69 or so. Definitely worth the investment!
These seem to work great for keeping quantities of hops fresh, and odour free in your freezer! I was able to fit about 20 ounces of hops into 2 of the bags that came with the kit.
EDIT: I was using a 1 gallon bag to house an OM10 mask (filters in), and noticed after a week that there was air in the bag. (Though you shouldn't have a problem keeping hops fresh, it was a matter of the mask being very large in the bag)
