Another issue I’ve had with tackle trays has been the obnoxious process of cutting and placing the dividers; if you don’t trim ’em just right, they won’t fit correctly and small terminal tackle items can slide under the dividers and create an unorganized mess.
Fortunately, the Plano EDGE 3500 Box comes with pre-cut vented dividers which also absorb water. When I first got this box, it took me about one minute to set everything up how I wanted it. The dividers fit perfectly and you don’t have to break out the scissors and go through that whole process. I unpacked it, took the label sticker off, threw in the dividers and within just a few minutes I had a fully stocked “emergency” pond/co-angling box.
