I have read the bad and the good reviews and unfortunately for me decided more on the positive reviews to hear. Was unfortunately a wrong decision. The cups are totally super on the size and the color also produces a looker. Unfortunately, the lid only it pressed and then coming back up a bit. whatever the lid on what can. Everything tasted. , Press the variant that you indeed know of Tupper with in the middle, so that the air escapes, and then push the edge. Unfortunately, try anything and press helped. The cups are thus leaky and not suitable for freezing and transporting.
