The foam keeps my flies organized and prevents tangling. The long slit works well for heavy nymph patterns. I use the large size and it holds 90 flies easily. No issues with hook deformation after several months of use.

Great for storing attractor flies and Salmonfly patterns. The micro slit adjustment helps protect the hook. I noticed less wear compared to previous foam inserts. Slightly bulky but worth it for storage.

I switched from plastic inserts to this foam and it’s a big improvement. The depth adjustment keeps the hook safe. The large size fits perfectly in my fly box and holds all my patterns neatly.
