This is a set of three glass food storage containers and an electric pump from cielob. I am selling these because I haven't been able to successfully create a vacuum and haven't been able to use them properly. The vacuum state fluctuates depending on the operating method. I tried several times, but I couldn't find any visible damage to the lids, so I don't know the cause. It may be a problem with my operating method. To avoid any trouble after purchase, I am selling these mainly as glass containers and an electric pump. Please understand and agree before purchasing. Everything in the photos is included. You can charge it with your own cable cord. Stored at home. Available for immediate purchase.
