Mike,
I've got a good number of pieces like these in the pick, they've been kiln dried in my 'mini-kiln', so all the critters that may have been in there at one time should be long gone or crispy critters.
I could put together a SFRB of this sort of stuff pretty easily, essentially stuffing it full for $15 shipped...if this would help. I would likely include one of the larger 1.8"sq x 8" long pieces, a couple of the 7/8"x1.5x 8" types and the balance in 1" sq (some may be closer to 7/8" on one side) pieces. Just let me know if you want it mostly 'plain' or prefer some spalting...I have some of both in these sizes.
If you need more or something larger, let me know what you're wanting to use it for and I'll see what may fit the need better. I do have some larger stuff, but not kiln dried, though it's been drying for some time (over 1 year) naturally.
