I really don't want to freak anyone out but I am certain that the manor I dunked - and warped- had fibreboard between the two layers of leather on the flap.
I actually removed the turnlock and pried open the leather cutout to see the insides. I had been hoping to perhaps build up the low points in the now buckled cardboard, using something that wouldn't cause mold to grow ( I'm still thinking through this idea). Anyway, the inside is positively fibreboard. I am certain now that I warped both of my Manors, it's just very minor on one of them and wouldn't have noticed if I didn't reference the 'before' photos.
It is certainly posdible that I didn't flatten the flap properly when drying. Perhaps I just didn't weigh it down for long enough? Perhaps the buckling occured slowly with a still damp interior layer when the outside seemed dry? I remember being concerned about mold growth and may have just not given enough drying time weighted.
If I were to buy a Manor again I would not dunk unless I really had to. That's just my experience though!
If you do dunk, I believe that the fibreboard also runs under the handle, and along the back top of the bag. That's where the warping is for me on my other bag. So I would work out some way to weight that whole paneled section when drying. If you feel along that area you can feel the stiffener in there.
Finally - and this might seem bonkers - but I would also clean the ring on the flap for turnlock and put it back before dunking, as it will help align the leather layers and fibreboard when drying. Just allow for that protrusion when drying the flap - say by cutting a hole in the board your using to flatten the flap.
I hope that's a bit helpful? If not, just ignore. I might just be unlucky with this style bag![]()
Do you happen to have pics of the warped bag? Also...I hate to ask, no offense intended....are you sure the bag is authentic if it does indeed contain fibreboard? I'm just speculating here, I have no idea if Coach would use cardboard or not. But apparently they did in the binocular bag, so who knows. I just don't want it to be true!
