Is this Nike authentic?

Yes. Every CLB XXIII piece is physically inspected and authenticated by our in-house team before it is listed. We verify serial numbers, hardware, stitching, and materials by hand, and back it with a lifetime authenticity guarantee — if any item is ever proven not authentic, you receive a 100% refund with no time limit.

What condition is this item in?

Each piece is hand-graded into one of six standardized condition tiers (Pristine, Excellent, Very Good, Good, Fair, As Is). The exact grade and any included extras — box, dust bag, tags, authenticity card — are listed on the product page.

Because every piece is individually sourced under our one-of-one model, all sales are final and we do not accept change-of-mind returns. Before buying you can call us, request additional photos and measurements, or see the item in person at one of our Ohio stores. Items that arrive damaged or incorrect are resolved if reported within 48 hours of delivery.

Can I pick this up in store?

Yes. Same-day local pickup is available at our Cincinnati (Kenwood) and Beavercreek (Fairfield Commons) locations. Select your preferred option at checkout.

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.
