Reference apparatus and storage and dispensing apparatus (such as for storing and/or dispensing the reference apparatus) are disclosed. In some embodiments, the reference apparatus may include a unitary planar material having a first panel, a second panel, and a third panel disposed between the first and second panels. The first and second panels may be configured to be folded between a folded position in which the first and second panels are parallel to the third panel, and an unfolded position in which the first and second panels are coplanar with the third panel relative to the folded position. One of the first and second panels may include an attachment portion configured to receive a receiving portion of the other of the first and second panels to secure the first, second, and third panels together in the folded position.
