This is the second roll of straight pins I've had in the shop--a beautiful readymade if I ever saw one! I'm always eying antique pin cushions, too, where someone's name or a message was painstakingly spelled out in pin heads, which makes this feel like a big roll of decorative potential to me. This roll was wade by Monarch, c. 1950s or so, and though it's certainly lost a few, it looks like most of the original 5000 remain!
5 5/8" in diameter including cardboard x 1 1/8" tall.
