Rough Brazil agate nodules, extra small, are nodules sized approximately from 1/4th of a pound to one pound plus each. (Stock 107) An order of one will give you Brazil agate nodules to add up to approximately 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. See the Lapidary Tips category for information on Slabbing small or round rough rocks.
