WFS is an online database documenting character figures and garage kits displayed or sold at Japanese hobby events from 2005 to 2015. It focuses on cute, character-based scale figures and excludes overtly sexual works. Visitors can browse the collection by event, dealer, creator, original title, or character, or search across the full catalogue. Event listings cover Wonder Festival and other gatherings, including Treasure Festa, Character Hobby, and Hobby Complex. The site also features reports from selected events, offering a record of exhibitions and the works presented there.

Alongside its database, WFS provides practical resources for garage-kit event visitors, with guides covering preparation, attending an event, photographing displays, and presentation methods. A glossary, frequently asked questions, and information about counterfeit kits offer additional context for hobbyists and collectors. Users can save up to 100 favorite works and submit comments or other posts through the site. WFS also links to event, dealer, and hobby-report resources. It is a reference and community resource for exploring the history and creators of event garage kits.
