Shipping & Delivery Updates

We understand how important it is for you to receive your orders on time, and we sincerely apologize for any delays you may be experiencing with your shipments.

Please note that once packages leave our facility, they are handled by third-party carriers, such as the United States Postal Service (USPS). While we do our best to ensure timely dispatch, delivery times are ultimately out of our control once the package is with the carrier.

We greatly appreciate your understanding and patience. Please feel free to reach out to our customer service team if you have any concerns or need assistance tracking your package.
