Rough Brazil agate nodules, extra small, are nodules sized approximately from 1/4th of a pound to two pound plus each. (Stock 107) An order of one is for one pound. The image shows an extra small Brazil nodule next to a four pound nodule. The small size is nice for craft items such as wind chimes, butterfly designs, pendants, etc.  To easily slab these small nodules, some use a trim saw and others use a Plaster of Paris mold. Also slab one in half and glue to a board then slab to size needed. See the Lapidary Tips category for information on Slabbing small or round rough rocks.
