27L 1940s White Casein Four-Hole Buttons 5/8 Inches Set of 6

Set of six white casein buttons dating to the early 1940s, a peak period for casein button production when matte finishes in neutral tones like white were popular for everyday and utilitarian garments during and after World War II. This aligns with the simple, practical design seen here, which was mass-produced for shirts and workwear.
