I love these fly cups for field testing my flies! Oftentimes, I have 1 or 2 experimental patterns to field test and this is all I need to carry those flies in for that purpose... These little fly cups are great when you don't need to carry a fly box. They take up minimal space, will fit in a pocket and they're plenty big enough for what I got them for. I like how the lid is attached too and they're fairly sturdy as well. At this price point, it's well worth having a couple on hand...
