This 12 bottle Polysafe shipping box contains 2 x 6 bottle polystyrene moulded bases and matching covers, supplied with a corrugated cardboard outer box to hold the contents. Designed to hold and keep 12 bottles of champagne or wine safe in transit, as well as any bottles that are of a similar size. Quite frankly, it’s the ideal bottle transit packaging solution, it even keeps your bottles at the optimum temperature during transit thanks to being insulated. The benefit of using our 12 bottle Polysafe postal pack instead of the Mailsafe postal packs, is that the polystyrene completely surrounds the bottles in individual compartments, ensuring the bottles don’t knock together or break in transit.
