This is a cup with changeable tops. When you are short on space (or want to save money) this is a greata option. As you can see on the label it's designed to take baby through the different stages starting with drinking from a bottle around 2-3 months. At 5 months you switch to a sippy cup style top and at 8 months to a straw or open cup top. Little guy wasn't a huge fan of the first two tops but I chalk that up to his using a natural-style nipple bottle. Now he uses the starw top most of the time. I don't have a picture of the case but we did get an insulated case which can be used to keep drinks warm or cool.
This cup set is by far one of the most useful things we bought.
