Aristocob has a kit that includes almost 2 dozen corn seeds that are from Missouri Meerschaum (MM) (the same ones they use to make their cobs). MM has bred this particular strain to be big with nice thick side walls. Price is about $10.00 and includes 2 shanks and stems for making your own pipe. Get 'em while they last.
