So I ended up going to Canadian Tire and grabbing these:
I wet one very well with DW and put it on a plate and put the plate in the top tray in my Klip-It
Here's how it looks now...
And here it is resting beside my bed on my CD storage box/nightstand for stuff resting and doing its thing.
One question though, given at how thick the sponge is (it's basically
touching the inside of the lid of the Klip-It when I put the lid on it and sealed the Klip-It shut) will that mess up the seasoning process if its touching the inside of the lid???
