This is a drop that has the mandrel going top to bottom, through the length of the bead. This is a very versitile tool, and can be used for drop pendants or charms, they can be turned into leaves as I did (all it takes is a little work with the razor tool or and exacto knife). Very nice shape with plenty of surface space for decorating! Dimensions: Small: 19mm top to bottom (3/4"), 12mm across the widest point of the drop, and 7mm thick. Medium: 25mm top to bottom (1"), 17mm across the widest point of the drop, and 7mm thick.
