Unfortunately I don't have any more packaging, but I might buy another one. ?
The receipt only says what the "lids" are called. (see title)

@Migros
I am thrilled! ?

Dear forum members - Perfect. Take a look at them. I have found a link that shows you what I mean.

Ingenious, the lids from the Kochblume still have an edge finish, are slipped over.
These silicone lids are extremely stretchy and also great for larger items.
So completely different, but that's exactly what I was missing.
