Fuji Enamel Chef Lock Rectangular with built-in air extraction pump You can easily preserve food by simply pressing the pump to extract air! The transparent container allows you to clearly see the contents, making it very convenient for storage! Double valve + silicone packing prevents odor leakage! Excellent airtightness! Shuts out air! Prevents food oxidation and preserves deliciousness! Enjoy your breakfast! A whole loaf of bread fits inside! Usable capacity: 4.0L I've been using one, and it's rare to find one with a built-in air extraction system. It's easy and convenient to use, just push the pump to remove the air. I bought this as a spare, but the one I'm using hasn't broken, so I've kept this one unused in a bag. There don't seem to be any noticeable scratches, but since it's a product without a box, there are slight scuffs on the bottom. This is a personal item stored at home, so please purchase it if you don't mind.
