Super Slim Waterproof Magnetic Fly Fishing Box - 12 Compartments, Black (2 Pack) | Perfect for Fly Storage & Outdoor Fishing Trips

My first impression is that these are heavier than I expected. This is my first magnetic fly boxes I have owned. They come in a set of two and I was surprised at the heft of the package. Of course, that makes sense that the magnetic material weighs more than just the foam inserts that most fly boxes have. After putting some weighted nymphs in them, I was pleasantly surprised to see the magnets perform. They keep the flies in place but they are not so strong that makes retrieving the flies difficult. It is a really good setup. I got these for the purpose of storing small flies, size 18 and numerically smaller. Keeping them in the foam keepers is challenging and they usually end up all scattered inside my the fly box. This magnetic box is the perfect solution to keep everything sorted without having to be so particular about how they get put away. I'm sure they'll work fine for larger flies too, but for my purpose, these are about perfect. An added benefit is I can store more flies per box than I can with my foam boxes. So my pack will be less bulky with these. That you get two low-profile fly boxes for the price of one standard foam fly box makes these a particularly good bargain.
