We package all our boxes so that they will withstand up to 48 hours in the courier system, as DPD does sometimes incur delays. Each item is sealed individually within our boxes. We also use eco WoolCool to insulate our boxes against outside temperatures and ice packs to insure the interior of the box maintains a steady temperature. It is normal for the ice packs to melt somewhat during the delivery process. This can sometimes cause a little condensation/water damage to the outside of the box/packaging but should not affect the product inside. If you do have any enquiries regarding a delayed box it is best to email us directly via our Contact page.
