One of the things I've been doing during quarantine is send out handwritten letters to some of my friends and family, because everyone likes getting something in the mail. And because I'm me (passionate about both history and stationery), I've been using old-fashioned wax seals on the envelopes (using a modern stamp bought on Amazon).
Well, on eBay I just found this antique stamp that happens to have my initials carved on it. How cool is that? Got it in the mail today, and it works great.
