Nice photos, as always, and great descriptive write-up. But how do you *close* the lid such that one side's pieces don't tumble out?
Edit: On multiple viewings I realized I was getting confused by the way the images depicted both sides next to each other as if they closed together. So it's one box per color?
I am officially on Team Plano. Throughout the years, Plano organizer storage boxes have been mentioned here on CB&E forum as handy, cheap, reliable, and compact. At $8 each, and made in the USA you really can't go wrong with it. The 3700 size has several different models.
3700 Stowaway with ProLatch.
3700 Stowaway Rustrictor with old style latch.
3700 Edge new design, hard plastic.
The 3700 Stowaway with ProLatch has 2 styles. Style "A" has 4 customizable rows. Style "B" has 2 customizable rows, plus 1 double width row. Style "A" and Style "B" are exactly the same construction. Beefy latch. Thick reinforcements along edges for more rigidity. Stronger hinges. The only difference between A and B are the different row configuration.
The 3700 Stowaway Rustrictor with old style latch is a bit on the flimsy side compared to the Stowaway with ProLatch. There's not as much reinforcements along the edges. The hinges are weaker. The latch is thin. It's a nice box on it's own, but when you have it side-by-side with the Stowaway Prolatch the differences are immediately noticeable. They are relatively the same price. The one benefit of the Rustrictor vs the ProLatch is that the Rustrictor rows have twice as many divider holder slots than the ProLatch to make it more customizable.
The 3700 Edge is a new design with hard plastic. Whereas the ProLatch and Rustrictor have a "Tupperware" style plastic that has a bit of give to it. The 3700 Edge is made from a hard plastic. Metal pins in the hinges. Along the 4 rows it has even MORE divider holder slots to make it the most customizable of the bunch I tested. I really wanted this 3700 Edge to suit my needs. BUT one small measurement was excruciatingly off for my needs. When the Sinquefield set King is laid on it's side, the depth of the box was 2 millimeters too shallow. The lid comes in contact with the King base. The lid ever so slightly flexes at the point of contact when it is closed and the latches are locked. So disappointing. Ohh,, and the 3700 Edge is made in China, if it matters to you.
Here are pics of the Plano 3700 Stowaway ProLatch with my 3.75" King Sinquefield set from HoS. I lined the bottoms with $3 worth of 1/4" thick felt furniture pads. They come in sheets, and you just trim what you need.
At almost 3x the price of the 3700 ProLatch, the 3700 Edge is quite the upgrade in strength, rigidity, and customization. Be careful of the King Base. A 1.75" King base will make contact with the lid. Still useable. It will close and lock. Just really snug.
