For sale is a lot of 2 vintage rock-collection pencil-vials!  The pencil is both an unsharpened pencil, and a vial containing semi-precious gemstones such as snowflake obsidian, amethyst, tiger's eye, quartz, agate, garnet, and so on.  The pictures show an example lot.  They are unused and the erasers are unused as well.  The colour of the central band varies.  Some pencils are white-bodied, others natural wooden.
