The FoodSaver Fresh Containers 10 Piece Set is a vacuum sealing system accessory designed to preserve food by removing air from the packaging. These containers are made of clear plastic and come with a 1-year manufacturer warranty. They are fridge and freezer safe, dishwasher safe, and BPA-free. The set includes 10 pieces: 4 multifunctional containers (two each of 3 cup and 5 cup capacity) that can be used for various food items.

Vacuum is applied either with a food “Seal-a-meal machine (rather bulky) or the much easier and compact rechargeable hand held vacuum pump. These little “air suckers” are about the size of a cafe salt shaker, and stow easily in the drawer. I’ll include a photo of the vacuum pump, which is NOT included in this sale, for we are using it all the time. The handy little pump is available from FoodSaver's web page, and probably multiple other on line retailers. The price is around $30 and higher, depending on where you purchase it, and whether you need the "FoodSaver" logo on it.

What we are selling is a set of the containers, which we already have plenty of and are redundant. The ones we are using are exactly like these, have worked perfect for a decade, and keep our fruits, leftovers, cheese, etc. quite fresh. 

Another usage is for refrigerated marinade of meats, which we have not done, for we are vegetarian. Your mileage may vary...
