That is interesting ply. It is not what I was thinking the baltic birch is solid birch exterior and cores. It is glued with urea formaldehyde glues and needs to be fully sealed. (it needs to be anyway so no big deal) They are odd sizes being 60 inches square. But far cheaper than the ply you quoted and more laminations.
