Every year, I send friends in the 4 corners of the world around
Swiss panoramic calendars.
Until recently, these calendars were accompanied by a box
accompanied by a cardboard box so they could be sent by post.
Nowadays, unfortunately, these calendars are sold without
mailing cartons. Why is this? I'm sure that the majority
of these calendars would be sent abroad. But how can we
to send them without having to buy very expensive
expensive boxes?
