The Onnis is an online shopping platform focused on buying and selling Korean products, with international shipping highlighted as part of its offering. The site brings together several ways to shop, including a general store, Bunjang&Trade, and a custom-order service. These options give customers routes to browse available products or seek help obtaining items through a tailored request.

The homepage also features new arrivals and sale items, while product listings can be explored through search. Shoppers can create an account to manage orders, downloads, addresses, and account details, and registered users can save products to a wishlist. The Onnis provides practical customer information through its shipping policy, returns page, order-status service, and contact section.

It also publishes a blog and maintains links to social channels, including Instagram and TikTok. Although the available site text does not specify particular product categories or describe the custom-order process in detail, it presents The Onnis as a Korean-product marketplace serving customers who want to shop across borders
