Anybody out there using these?  I know they're not waterproof but some of the sizes are intriguing, particularly the smaller options.  Just wondering if anyone can provide insight on construction/durability, etc.

I use the 3600 size as an open compartment box for packs of 4-7inch straight tail worms. I really like the quality and build, I highly recommend them.

i use a couple of the smaller ones for jig heads ned heads drop shot weights etc. great quality and you can make the compartments any size you want.

I have one of the smaller sizes and the quality is really good. There are similar/same to some Orvis boxes I have and those have been good as well. I have the sub 3600 size that I use to store treble hooks. The only bummer is I really like that size but since they aren't common there is no tackle bag for them. That is why I never bought more than two of the Orvis branded ones or more of these.

I didn’t know about these. Now it’s on my radar. Thanks a lot friend.

Thanks for the replies guys! I'm definitely gonna pick some up!

I keep one of the slit foam boxes with an assortment of swing heads, swimbait heads and belly weighted hooks. I've had it for two seasons now and no complaints. Well built and the single latch is nice.

If you store them so the shorter side is down, the dividers that run from hinge to clamp (front to back) can flex and pop out in bigger water.   That being said I use as a treble bait box when co angling.
