Our warehouse makes the preparations for the icebox or ice packs just before packing the order. The ice might have melted during shipment but since it is insulated well and there is no opportunity for air to get inside, the temperature remains below 8°C which is an acceptable temperature for up to 7-8 days. In some cases with products such as Innotox, their manufacturers informed us that it has heat resistance and it can be stored* up to 40°C as it is already diluted. (*It is still highly recommended to store the product in the fridge upon receipt of your package) Please check your ice-cooled products specific requirements in their dedicated product description or contact us if you are unsure about how to store your product.
