The Magic Fine Quilting pin is 0.5mm thick and 1 3/4" long. It is longer than the fine Magic Patchwork and Silk pins and more what you might think of as a 'quilt pin'.

Fine Magic Pins are a little bit flexible and come to a very sharp point. The plastic end of the pin is ridged to make it easier to hold. The plastic is heat resistant to prevent melting during ironing. The head isn't bulky which will make it lay flatter as you sew on the machine. I really like these pins for piecing.
