    In-stock orders are typically processed and shipped within 1–2 business days of receiving payment, unless otherwise stated on the product page. Orders placed on weekends or holidays will be processed on the next business day.

    Shipping Costs

    Shipping costs are calculated based on the shipping method selected, the weight and dimensions of the package, and the destination address. You can view the shipping costs for your order during the checkout process before finalizing your purchase.

    Tracking Information

    Once your order has been shipped, you will receive a shipping confirmation email with tracking information. You can use this information to track the status of your package and monitor its delivery progress.

    Delivery Time

    While we make every effort to ensure timely delivery, please note that delivery times may vary due to factors beyond our control, such as weather conditions or carrier delays.

These additional charges are the responsibility of the recipient and are not included in the shipping cost paid at checkout. Please check with your local customs office for information on potential fees before placing your order.

    The cost of return shipping is the responsibility of the buyer unless the item was received damaged, defective, or incorrect.

    Return Authorization

    Before returning any item, please contact our customer service team to obtain a Return Merchandise Authorization (RMA) number. Items returned without an RMA may not be accepted.
