This box is very well designed to keep the salad at best: it avoids that it rests on a layer of water through a removable grill which avoids contact with the bottom. The result is very positive: no leaves "faded" and flanges. The salad really stays fresh longer. The size (especially height less than 12cm) of the box is ideal for a fridge. Spacious enough and not too high to switch smoothly between the shelves. The closure system is also convenient and reliable. The plastic used seems both firm, solid and flexible enough not to break easily.
