When products are shipped, great care is taken to ensure their safe delivery right to your home or office. However, please keep in mind that in extreme heat, your products can be affected. We will use the best packaging material to prevent any issues as well as external box labels for the carrier, such as, "Keep out of Heat/Sun". When placing your order, you are aware changes may take place during transit that is out of our control. Therefore, be mindful of this prior to placing your order. Thus far, we have had no issues with any problems due to shipping during exceptionally hot summers or extremely cold winters.
