I'll throw in a few extra dice that I bought along with these, but pictured are the best of them. The blacks on the bone dice, all 19th century, are wonderfully irregular; I especially love the curling arcs of the threes. The red one is wooden, and an early one. Nice just thrown in a bowl, but there is a pair here of the same size that would be good for any dice throwing game.
Red one measures 1/2" cubed. Largest bone is 7/16" cubed; medium pair 5/16" cubed; smallest 3/8" cubed. A few small chips to the bone ones here and there, which just add character I think.
