Wooden pot keeper holds the lid open so the water doesn't boil over With the funny beech wood pot guards, nothing more cooks over. This clever invention makes kitchen work easier and more cheerful. The pot guard is placed between the pot and pot lid so that there is a gap and water vapor can escape. The pot guards have a “leg width” of approx. 0.8 cm and are therefore not suitable for pots with particularly wide or curved edges.
