Since each bottle in Nubelle's Batch 01 contains live botanical actives and a high concentration of collagen, we don't use mass stock in regular warehouses. Your order undergoes a final stabilization and purity inspection process before being vacuum-sealed for shipment. This artisanal and technical care ensures that the formula arrives at your door with 100% of the effectiveness promised by our experts. The 5-10 business day delivery time reflects our commitment to the integrity of your treatment, including shipping in exclusive thermal protection packaging.
