Tacklebox for powerbaits/jars?

Anybody have any recommendations or links to a tacklebox similar to this? I need it to store my berkely gulp jars, because they tend to leak if they're on their sides, so I'm trying to scout out something like this plano box. Unfortunately my backpack is on the smaller side and won't be able to fit this box laying flat. Preferably something in the ballpark of 11x7x3inches.
