Unused Tupperware Lettuce Keeper and Core-All. Although it has never been used, it has been stored on a shelf at home without being in a bag, so I have listed it as "Like New." It is suitable for storing round leafy vegetables such as lettuce. You insert the core of the lettuce into the pointed part and close the lid to store it. It is said that it can keep lettuce crisp for a longer period than regular storage. Tupperware was an old-established storage container company in the United States, but it seems to have recently gone bankrupt. Since it is no longer sold at official stores, the chance to buy it new is probably through Mercari, etc. If you are interested, why not take this opportunity? Due to the difficulty of obtaining it, I will refrain from lowering the price at this time. Lettuce Core-All Lettuce Keeper Tupperware Tupperware Storage
