Our 6 bottle box protective outer is primarily used with our 6 bottle gift boxes but can also happily fit 3 x double bottle boxes too. When using the outer, the wine packaging can be sent out with couriers, but we recommend teaming them with bubble bags or elasticated sleeves around the bottles. These cardboard postal boxes are great for both online businesses and brick and mortar stores wanting to ship bottles of wine or champagne to their customers. The protective wine shipping boxes are printed with 'Fragile' on either side but to be extra safe we recommend using our red fragile tape when sealing your boxes. Also part of our 'Mailsafe' range, known as the outer carton for our reference M6.
