Zip lock bags has a starter kit includes one Vacuum Sealer Pump and three quart-size Vacuum Freezer Bags. They also have gallon size bags. For less than 4 bucks, you get the little hand pump and you put it on a spot on the upper right side of the bag that has a one way valve. Just pump it a few times and it sucks all the air out. I use a spray car wax on the inside of the bag as a release agent. It works great for small parts!
