Just posting a photo in regard to a question I had in a thread on here. I came in later in the day. So I’m unsure about other sizes being available. There was a stack of these sizes. But to compare; this one would be considered a large box. Dimensions included in the last photo. Post office clerk told me if we used the white ones, there’s a chance they can send it pack because it costs more. So beware. Happy Poshing!
