Any Experience With Cork Bulletin Board Panels?

[AbraxasComplex]

So before you tell me that Cork Bulletin Board Panels are hideous for a background I must tell you I am not using them as such.

I am asking this in the vivarium forum to gain any insight from your experiences with untreated cork flats you normally use as bulletin board panels.

I plan to take a large amount and create honeycomb like structures in my feeder bins. Cardboard egg crate has become a nuisance and I need a substance that will withstand high humidity as well as be nontoxic. I already use cork bark chunks, but have trouble removing smaller feeder bugs for cleaning purposes.

I was also contemplating coco-fiber sheets since I can purchase many feet off a large roll from my local garden store. I am just concerned the feeder bugs will consume it.

Any help concerning a cheap, easily climbable, durable material that I can stack or fix together vertically would be much appreciated.

that packing material they use to separate stuff and prevent denting while shipping might work. its a thin crimped/zigzag looking sheet of cardboard. i think they sell it at the uhaul stores for pretty cheap.
