Embodiments provide for a saw chain packaging that includes one or more features integral to the packaging that enable a customer to determine whether a chain not included in the saw chain packaging has one or more attributes that are the same as a saw chain included in the saw chain packaging. As one example, the one or more features include a pitch measurement section and a gauge measurement section, and the one or more attributes include saw chain pitch and saw chain gauge. In this way, customers may readily appreciate whether a particular saw chain will be appropriate for their particular saw, without having to purchase any tool or rely on any product material other than the saw chain (or portion thereof) the customer is seeking to replace.

Each column panel can be erected to form a rectangular column adjacent to each of the lateral edges of the main body panel.
