Shipping policy

At Core Box Lab, we want the process of receiving your hair accessories to be as convenient as choosing them. Whether your order includes headbands for everyday wear, claw clips for quick styling, or hair ties for keeping your hair neatly in place, this Shipping Policy explains how we handle order processing, shipping charges, dispatch, delivery estimates, and shipping-related questions.

1. Shipping Fees

We offer the following shipping arrangement for eligible orders:

  • Free shipping: Orders with a qualifying merchandise subtotal of US$10.00 or more.

  • Orders below US$10.00: A shipping fee of US$5.99 applies.

Unless otherwise indicated during checkout, the shipping threshold is calculated using the merchandise subtotal after applicable discounts and before taxes. The final shipping charge will be displayed in the checkout summary before payment is submitted.

All stated shipping amounts are in United States dollars (USD), unless the checkout page clearly indicates a different currency.

If a promotional offer provides different shipping terms, the conditions displayed with that offer will apply to the qualifying order.

2. Order Processing Time

After an order is submitted, it may need to pass through payment verification, order review, inventory confirmation, picking, packing, and dispatch preparation.

Our estimated processing time is generally 1–3 business days after an order has been successfully placed and payment has been authorized.

Business days generally exclude Saturdays, Sundays, and applicable public holidays.

Processing may take longer during:

  • Major promotional events.

  • Holiday shopping periods.

  • Unexpected inventory fluctuations.

  • Severe weather or operational interruptions.

  • Periods when payment or order details require additional verification.

An order confirmation indicates that we have received the order information. It does not necessarily mean that the parcel has already been dispatched.

3. Estimated Delivery Time

After dispatch, standard delivery is generally estimated to take 5–10 business days.

Based on the ordinary processing and transit estimates above, the overall estimated timeframe is approximately 6–13 business days from order placement.

These timeframes are estimates, not guaranteed delivery dates. Actual delivery may vary depending on the destination, carrier operations, weather, seasonal volume, customs procedures where applicable, and other circumstances outside our reasonable control.

Where a more specific delivery estimate is displayed at checkout or in an order confirmation, customers should refer to that information for the relevant order.

4. Dispatch Confirmation and Tracking

When tracking information is available, we may provide a shipping confirmation or tracking reference through the contact details supplied at checkout.

Tracking updates may not appear immediately after a parcel is handed to the carrier. Some delivery networks require time to scan and register a shipment before the tracking page displays movement.

Customers should check the tracking information periodically and ensure that their email address and other contact details are accurate.

If tracking information appears inactive for an unusually long period, please contact us with your order number so that we can review the shipment status.

5. Delivery Address Accuracy

Customers are responsible for providing a complete and accurate shipping address when placing an order.

Before submitting payment, please carefully check:

  • Recipient name.

  • Street address and apartment or unit number.

  • City and state.

  • ZIP code.

  • Contact information, where requested.

If you notice an error after placing an order, contact us immediately at [email protected].

We will make reasonable efforts to correct an address before dispatch. However, an address change cannot be guaranteed once an order has entered fulfillment or has been transferred to a carrier.

Additional delivery charges, re-delivery costs, or other consequences resulting from incorrect information may depend on the carrier's procedures and applicable law.

6. Delivery Attempts and Unsuccessful Deliveries

A carrier may make one or more delivery attempts according to its own procedures. A parcel may also be directed to a collection location, held for pickup, or marked as undeliverable.

If a parcel cannot be delivered because the address is incomplete, the recipient is unavailable, or the carrier cannot access the delivery location, customers should review the carrier's tracking instructions and contact us if assistance is needed.

We will review the available shipment information and consider reasonable next steps based on the circumstances.

7. Lost, Delayed, or Missing Packages

A parcel may occasionally experience a delay or an unexpected tracking status.

If your order has not arrived within the estimated delivery period, please contact us at [email protected] and provide:

  • Your order number.

  • The name used for the purchase.

  • The delivery address or relevant order details.

  • The tracking number, if one was provided.

  • A brief description of the delivery concern.

We will review the information available and, where appropriate, seek clarification from the carrier or relevant fulfillment provider.

A tracking status marked "delivered" does not by itself resolve every delivery concern. If you cannot locate the parcel, please check the delivery area, mailbox, parcel locker, building reception, or other customary delivery locations and contact us so that we can review the matter.

Any resolution will be determined in accordance with the facts and applicable consumer protection requirements.

8. Shipping Delays and Backorders

We make reasonable efforts to ship orders within the timeframe stated at checkout or otherwise communicated to customers.

If we learn that an order cannot be shipped within the applicable promised period, we will provide the required notice and explain the available options. Depending on the circumstances, customers may be asked to consent to a revised shipping date or may cancel the unshipped order and receive a refund.

We will comply with the Federal Trade Commission's Mail, Internet, or Telephone Order Merchandise Rule, including applicable requirements concerning shipment expectations, delay notices, customer consent, cancellation, and refunds.

We will not treat a shipping estimate as permission to delay an order indefinitely.

9. Incorrect, Damaged, or Incomplete Shipments

Please inspect your parcel after delivery.

If you receive the wrong product, a damaged accessory, or an order with missing items, contact [email protected] with your order number and relevant photographs.

For example, please tell us if:

  • A headband is missing from the package.

  • A claw clip arrives broken or visibly damaged.

  • The received hair ties differ materially from the order.

  • The package contains an incorrect product or quantity.

We will review the issue and determine an appropriate solution, including a replacement or refund where applicable.

10. Shipping Restrictions and Service Availability

Delivery availability may depend on the destination, carrier coverage, product availability, and operational requirements.

If a delivery destination cannot be served, or if a shipment cannot reasonably be completed, we may contact the customer to discuss cancellation, an alternative arrangement, or a refund as required by applicable law.

Any shipping restriction displayed at checkout or communicated before purchase should be reviewed before submitting an order.

11. Changes to Shipping Information

If you need to change an address, correct a recipient name, or update delivery instructions, contact us as soon as possible.

We cannot guarantee changes after dispatch. Once the carrier has possession of the parcel, any redirection or delivery adjustment may be subject to the carrier's available services and conditions.
