Hareline Flip Cap 4 Small 2 Long Compartment Box

What it is

A clear, durable plastic storage box with flip caps and six compartments, laid out as four small sections and two long sections. The lids close firmly, so it works both at the tying desk and in a vest or pack without spilling. It’s sized for keeping a day’s worth of flies organized by type.

What to tie with it

This isn’t a tying material you put on a hook; it’s what you use to sort and protect what you’ve tied. The small compartments are handy for separating dries by size or stage, and the long compartments fit longer-profile flies so you’re not crushing tails or hackle. It also works as a simple gift box when you’re handing a set of flies to someone.

Flies and the fish they're for

Use it as a “working box” for the patterns you actually plan to fish that day, and swap flies back in only after they’ve dried so you don’t trap moisture in the box. The long compartments make sense for streamer days—think trout in rivers, smallmouth in creeks and rivers, or schoolie stripers in moving water—while the smaller compartments keep dry flies sorted for trout on tailwaters or freestones. It’s just as useful on the water as it is on the bench when you’re staging the next batch of flies.

How it compares

Hareline’s 12 Compartment Box and 21 Compartment Box are larger options if you want more separate slots than the six-compartment layout here.
