Shipping policy

Last updated: July 27, 2026

Shipping area

SI STUDIO currently ships only to eligible addresses within the United States. International shipping is not available.

Order processing

Orders are generally processed within 1–3 business days after payment is confirmed. Business days are Monday through Friday, excluding U.S. federal holidays. Order verification, peak sales periods, severe weather, inventory issues, or other exceptional circumstances may extend processing time.

Processing time is separate from carrier transit time. Express shipping does not change the stated processing time unless we expressly confirm otherwise.

Shipping rates

Standard shipping for 1–4 items: $12 USD
Standard shipping for 5 or more items: Free
Express shipping: $20 USD

The five-item free-shipping offer applies only to Standard shipping. Eligibility is based on the number of qualifying items in the cart at checkout. Applicable taxes, if any, are displayed at checkout.

Carriers

Orders are usually shipped through UPS or UniUni. SI STUDIO selects the carrier and service based on destination, package characteristics, service availability, and operational needs. Customers may request a carrier before fulfillment, but a particular carrier cannot be guaranteed.

Delivery estimates

Transit times and delivery dates shown at checkout, in tracking, or in communications are estimates unless expressly identified as guaranteed. Actual delivery may be affected by carrier operations, weather, holidays, peak-volume periods, address issues, or events outside our reasonable control.

Tracking

When tracking is available, it will be sent to the email address or phone number provided with the order after shipment. Tracking may take time to update after a label is created or after the carrier receives the package.

Shipping-address changes

Review your shipping address carefully before submitting your order. If an address needs to be changed, email wowowoperation@gmail.com immediately. We can attempt a change only before fulfillment, and a change is not guaranteed.

If a package is returned because the customer-supplied address was incomplete, incorrect, or undeliverable, additional shipping charges may apply before reshipment, except where prohibited by law.

Delayed, missing, or damaged packages

If tracking has not updated for an unusual period, a package appears lost, or a package arrives damaged, contact wowowoperation@gmail.com with your order number and relevant photographs or tracking details. We will review the shipment and, where appropriate, work with the carrier to investigate.

If tracking shows “delivered” but you cannot locate the package, check the delivery area, household members, neighbors, building staff, and any carrier notice, then contact us promptly. Carrier investigations may require additional information from the recipient.

For a damaged item, contact us preferably within 48 hours after delivery and keep the product, shipping label, and packaging while the issue is reviewed. This request does not shorten any non-waivable legal right.

Split shipments

We may ship an order in more than one package when reasonably necessary. Separate packages may have different tracking numbers and delivery dates. No additional shipping charge will be added solely because we split a shipment.
