From an estate. Pen measures +/- 5-3/4"l x 7/32" diameter. Looks like a ridged Mother of Pearl and gold to me but I'm no expert. Case measures +/- 7-3/4"l x 1-1/16"w x 13/16" thick. No clue what the date on the inside top lid signifies. Please ask any questions. As-is, as-found.
Handling time completely dependent on eBay release of funds, generally 5-6 days.
