The foam fits my crab flies perfectly. I can store up to 50 flies in the large size and adjust the slit spacing to match different patterns. It’s durable and keeps the flies dry during transport.

Great for organizing shrimp and crab patterns. The small size works well for lighter flies, and the medium holds enough for regular use. Easy to clean and fits neatly in my tackle box.

I’ve used this foam for several months and it still holds its shape. The 8mm thickness supports heavy epoxy flies without warping. The slit design allows for easy access and organization.
