Question about Korbell Refill foil

The 16-litre refill cassettes fit into the Korbell nappy bin with a volume of 15 to 16 litres. Larger pails are not explicitly mentioned in the available information, so it is not certain whether the 16-litre cassettes also fit in significantly larger models. The refill cassettes are specially designed for the Korbell nappy pail with a volume of approx. 15-16 litres.

No! I ordered these by mistake because they are the only ones. The 26-litre bucket also looks absolutely identical to the 16-litre buckets in the pictures, but these foils here don't fit on the oval element in the 26-litre bucket.
