Lettuce Keeper I bought this intending to use it, but I've never used it. I lost the koala-shaped core remover without ever using it, so the koala is not included. It's convenient because you can peel off as much as you need. It also features a dome-shaped center on the seal (lid) that conforms to the shape of the lettuce. Diameter: 20.2 cm, Height: 13.9 cm, Capacity: 2,800ml Although it's unused, there are some scratches due to home storage. I have other items for sale. Bulk purchases are welcome.
