D21 Freezer Mates Medium Low 1.1L
Controversial! After all these years, Tupperware has redesigned the freezer boxes! If you still have the old style so-called Double Diner and Shallow Diner, and you need a spare part lid or base, I have them here.
This is the Medium Low 1L size. You can also get it as part of the D23 Freezer Mates Starter Set. To see all the sizes of Freezer Mates, browse my Freezing collection.
Like the iconic D09 Freezer Double Diner, which it has replaced, the Freezer Mates work so well because the design facilitates maximum air flow in the freezer. They also stay flexible at freezer temperatures.
There are two slight improvements on the Freezer Square Rounds. When you stack them, the recessed top and slightly concave base help with the air flow. Plus, they also have a no-stain coating to prevent the age-old problem of staining from hot food with a high colour.
