This is a well-thought out set of 4 mugs with interchangeable drink toppers.
Each mug comes with a drink "pod" that forms the bulk of the drink. The kids can then choose from 4 different 'drinks' : Hot chocolate with marshmallows, Latte and Flat White with Coffee Art and a BabyCino.
These are made as toppers that fit on top of the drink pod. There are 2 of each topper included. You can also use the back to have tea.
