65     (Later Series)    Shaving insert
66     (Later Series)    Shaving mug

Do these shapes appear in other series?  No, not in other series (none recorded) but the shaving insert appears to be the same shape as Later Series 78 which is also described as a Jelly Mould.
It is not clear how the mug and insert were meant to function. The two are listed as being the same height.

There are no numbered examples in the image database.  Shape book entries provide the only information.
