I ordered this to replace a 3600 tray that held my yum dingers, senkos and tubes.It is a much better soft bait organizer for my use since I use a smaller tackle bag.The 5 bags inside seem to be fairly thick plastic, and they seal well even with some salt in the way. They are attached with Velcro at the base, I haven't removed them to see how secure they are but haven't worried about them coming loose either.I was able to fit 3+ bags of larger tubes, a slew of smaller senkos and some other miscellaneous soft baits.The Velcro closure on the outside allows for plenty of room to keep this thing closed even if you stuffed the bags with baits.It's a bit on the smaller side, but I definitely appreciate the form factor, and it makes it super easy to grab the bait I'm looking for.If you use grubs, tubes, senkos or similar, and you're tired of carrying 6+ bags around and digging for the right one this is a solid solution that'll keep your soft baits as good, if not better than their own packaging.
