What series are the slim tackle boxes? Looking to pick up a few for my terminal tackle and jigs

3771 is Plano's slim custom box.

They also make a slim 3600 box but iit doesn't have the custom dividers like the 3771, can't remember the model number for the 3600 slim

Plano 3701 is another slim box same as 3771 just with regular dividers. Word of advice get the 3771 the customizable dividers come in real handy.

I use the 3700 clear plastic boxes but one is deep while the 3701 or 3600 is thinner I'm not sure of the number. I find the 3700's in a four pack on Amazon.com

I use both the deeper and thinner for larger body cranks and smaller cranks and jig storage.

Thanks for the replies fellas. Gonna look into the 3771.
