If you are reading this review chances are you have had your things get wet on a marvelous kayak adventure. That can no longer be a problem by using this box to keep your things dry. Small and compact but useful enough to hold many things. I have 4 of these boxes that I stack in my milk crate. 2 orange and 2 blue. I use them to hold my headlamp, batteries, flammables, toiletries, and I use a slightly larger one to hold my pistol and ammo. 

Dimensions of this specific box are L 5.25 x W 7.0 x H 3.5 and weighs in at just a half a pound. The bigger unit is 6.75 x 8 x 4 and weighs just a tad more and is also about five dollars more. These come in two colors... orange and blue. and have a strap on them so you can tie them off to something. I have yet to experience one of these leaking. Plus they float!!
