The Umpqua UPG Foam Tailwater Fly Box is a high-capacity foam box for carrying a lot of small flies in a single case. In the Large, Umpqua uses a Micro Slit Insert for storing small patterns, paired with flat foam so flies sit securely but are still easy to pull. A magnetic insert adds a dedicated spot for small flies you want to access quickly. Umpqua also uses multiple entry points to help keep different sections organized instead of turning into one crowded panel. The Large is rated for 501 flies and measures 7.25" x 4" x 0.9".
