Some are metal; others are brass. There are glass ones, plastic ones, and wooden ones. There are LARGE ones, small ones, Sew-Through, Shank, and More.

They also come in a COOL & VINTAGE Tetley ”Hundreds” Tea Bags Lidded Tin!
Ask all the questions you want. I don’t know a thing about buttons, but they gotta go!
All it takes is $7.50 to start ‘em!
