I bought all these c&f and five inserts for $100 at sportsman warehouse when they were in bankruptcy. I bought all they had. It was about 60% off so I'm not complaining. I like the big box because I have big hands. The ridges give you a good grip on the box too. Plus they're waterproof and well made. Unfortunately that box doesn't fit anywhere on my person.
The small ones are slick and don't fit my hands well so they go flying once in a while and they're Not waterproof. I'm about ready to put some grip tape on them. They don't fit very well in pockets either.
