The Gruv Fishing Storage Boxes feature magnetic enclosures that hold the lids closed instead of traditional latches. There are round magnets spaced around the clear plastic lid and the solid plastic body of the boxes.
One thing I did notice on the Hard Bait Box, I had to make sure the crankbaits were all seated down into the silicone grooves all the way to make sure the lid and bottom magnets would connect. But once all the magnets were touching the lid stayed closed. I even could turn the boxes upside down and the lids would stay sealed. I’m not sure how waterproof the enclosure stays.
