## 1. Company Overview
CLB23 (legal/brand name CLB XXIII) is an independent luxury resale marketplace based in the United States, operating in USD. The business sources, authenticates, curates, and resells highly sought-after luxury and streetwear products from leading global brands.
CLB23's edge is scarcity. The catalog is built around archived releases, limited collaborations, one-of-one pieces, rare grails, and investment-grade products — the items that are difficult to find through conventional retail or mass-market resellers.

- Limited-release and archived streetwear
- Rare collectibles and art
- One-of-one and grail-tier pieces
- Investment-grade fashion and accessories
Inventory is curated and listed individually. Many products exist in a quantity of one, in a single size. Because of this, pricing and availability shift constantly, and the live product page should always be treated as the source of truth.
