Boat Cigar Storage Box!

A great storage option for all kinds of things. This one box can handle flys, credit cards, licenses, pocket knives, or… cigars! Yes that’s right, throw your favorite stogies in this bad boy and don’t worry about them getting crushed or wet. If I could give this box 6.5/5 stars I would. It’s the perfect size to carry everything for the armature fly fisher, or someone that wants to keep their Churchill’s dry and close at hand!

Great boat box!

I bought this for my husband as a gift. Makes it easier to row a raft and have the flies to tie onto our girls' rods much easier! They are close at hand when needed. He loves it ! Thanks!

Perfection in a small package

The Big Water Case is simply perfection is a small package, but don't let its small size fool you. Weather chasing down trout, hitting the rapids or out kayak fishing this car is a powerhouse. Plenty enough room to store all of your essentials , plus a trick load of flies! What more could you ask for?

Perfect river wallet

This thing is great! Solid box with some organizational versatility. The ability to tie it down is a big win. Perfect for day to day use and multi-day float trips. Got one for my raft and will be getting one for my drift boat. Nice work Trxstle!
