This listing is for one (1) US Postal Stamp Pen Blank for Sierra style. These are cast to fit any Sierra style pen kit. This includes Sierra, Wall Street II, Monarch, Ares, Gatsby, and many more. These are created with actual used US Postal Stamps. I personally handcraft each one of these! No two will be alike. These are cast in Epoxy resign, and will need to be trimmed and trued before turning. If back ordered, please allow 3-4 days to ship.
