How do I place an order?

Customers can choose to checkout as a guest or log into their member account, then click "Add to Cart" below the product they wish to purchase. After adding all desired products to the cart, click "Shopping Cart" icon in the upper right corner of the website to begin the checkout process.

Can I apply a discount code after payment if I forgot to enter it before?

Our system is fully automated. Once an online order is confirmed, the system automatically arranges shipment according to the order contents and cannot be manually modified. Please ensure all details, including discount codes, are correct before completing payment.

When will my order be shipped?

We aim to ship orders within 3 business days after payment confirmation. Delivery times may be affected by holidays (such as Christmas, Chinese New Year, and Easter) or adverse weather conditions. Delivery notifications from the courier service will provide final confirmation. If customers are unable to receive delivery on time due to personal reasons, please contact the courier company directly to make arrangements. Customers are responsible for any additional fees incurred. Orders canceled due to the customer’s inability to arrange redelivery are non-refundable.

Can I modify or cancel my order?

Once an order is submitted and paid, modifications or cancellations are generally not permitted.
