I got a "mystery" bass tackle box every month for a year for a birthday gift. It was generally some off-the-wall brand soft plastics, a no-name crankbait, and an incomplete package of hooks. I think I got 2 or 3 decent crankbaits in that whole year.
Bought a mystery tackle box, I though it was pretty cool, are there any others out there?
Are you asking if there are other companies besides MTB doing this type of thing. The answer is yes. There are probably a dozen or more. I've not tried any so I can't say how they are.
