All orders are shipped in a thin but sturdy black cardboard box (19cm x 14.5cm x 1.8cm). Retropilot shipping boxes are custom designed to prevent bending and damage to your purchase. The shipping boxes are thin enough to easily fit in most conventional letterboxes. Within the box, your items will be packaged within a protective plastic sleeve which will help protect them if the box gets wet (e.g. rain during delivery).
