Creme de la Creme is a new product available in the USA from Austrian-based Josef Manner & Comp. AG.
They're the same type of creme-filled wafers that the Manner brand is known for, except round in shape and packaged in a Pringles style can.
Varieties include Mousse au Chocolat with Fine Chocolate, Vienna Almond with Fine Almond Creme, and Black Currant-Yoghurt with Real Black Currant Pieces.
The suggested retail price is $2.99 to $3.49 each. I imagine you can find them in import stores.
