Processing and delivery

We aim to ship every order within 24–48 hours of purchase. Delivery times shown at checkout are estimates from the date of dispatch. In any event, orders are delivered within 30 days of us accepting your order.

Insurance and signature

Every shipment is fully insured by CLB XXIII while in transit. Select items — typically higher-value pieces — require a signature on delivery. Once the package is signed for, responsibility for the item passes to you.

If you've specified a recipient other than yourself (for example, a gift), a signature at that address is accepted as proof of delivery.

International orders

Customs, duties, and import charges are the customer's responsibility and are not included in your order total. CLB XXIII is not liable for delays caused by destination customs clearance.

Delays outside our control

If a shipment is delayed by an event outside of our control, we'll contact you as soon as possible and take steps to minimize the impact. You're also responsible for ensuring the shipping address on file is correct.

All sales are final

Every piece we carry is individually sourced, inspected, and authenticated in-store before it's listed. Because of this one-of-one sourcing model, we do not accept change-of-mind returns or exchanges.

We want you to buy with confidence — so please reach out with any questions about condition, sizing, or authenticity before placing your order. Our team can send additional photos, measurements, or detailed condition notes on request.

Authenticity guarantee

If any item is ever proven to be not authentic, you receive 100% of your money back. No time limit, no exceptions.

Every piece passes in-store authentication by our team before listing. If a third-party authenticator ever determines an item is not genuine, contact us with the documentation and we'll refund the full purchase price.
