Answer Source

Product IDs can be whatever you want, although it is recomend you follow the reverse domain name style. But in the end there's no restriction over the naming of your product IDs. It also does not need to use your app bundle ID as a prefix.

From the source:

Q: I am implementing In App Purchase and must register my product identifiers. What are product identifiers and how do I create and use them in my application?

A: A product identifier is a string used to uniquely identify every product you wish to sell from your application. The App Store uses it to retrieve information about a product. It is a string identifier that can only contain alphanumeric (A-Z,a-z,0-9), underscore (_), and period (.) characters. You can use any sequence of these characters for your identifier. However, we recommend that you use the reverse domain name style (for example, com.companyname.application.productid) when creating your identifier.

So 'Level_Pack_1' —as in your example— would be a valid product id.
