We accept Visa, Mastercard, and American Express. All transactions are secured with 128-bit SSL encryption and processed in a PCI DSS–compliant environment. Your full card number is never accessible to us — we only retain your billing information, shipping details, and the last four digits of your card for reference.

Orders are processed within 1–2 business days (excluding weekends and holidays). Standard shipping within USA typically arrives in 3–5 business days after dispatch. You will receive a tracking number by email once your order ships. Please ensure your shipping address is accurate at checkout — we are not responsible for delays caused by carriers or incorrect addresses provided.

We currently ship to USA addresses only. Shipping rates are calculated at checkout based on product quantity, destination, and shipping method. We are not liable for shipping delays once your order has been transferred to the carrier.

We offer a 30-day return policy from the date you receive your item. To be eligible, the item must be unused, in its original condition, with all original packaging and tags intact. To start a return, contact us through the chat support on our website. Items sent back without prior authorization will not be accepted.

Once we receive and inspect your return, approved refunds are processed to your original payment method within 10 business days. Note that sale items and gift cards are non-returnable.

Please inspect your order upon receipt. If your item is defective, damaged, or incorrect, report the issue immediately through the chat support on our website. We will evaluate the issue and resolve it for you. Do not return the item before contacting us — returns sent without authorization will not be accepted.

We collect only the personal information necessary to process your order and provide our services — including contact details, payment information, and order history. Your information is never rented, sold, or shared with third parties beyond what is required to fulfill your order (e.g., shipping carriers, payment processors).

You have the right to access, correct, or request deletion of your personal data at any time. Submit a request through the chat support on our website. For full details, review our Privacy Policy.
