Small transparent rectangular box containing roughly 100 ultra-fine pins. They have Murano glass tips. These pins have a diametre of 0.40mm and are 36mm long. As they are ultra-fine, they can be left in place when machine stitching. However, care must be taken when using thicker fabrics as their fineness makes them more fragile and they may bend if they are misused. The box is covered with a label representing an Alsace lady with her pedal sewing machine. Use a cutter to open the box without damaging the label. Dimensions of box: 6 x 4cm – 0.5cm high. We have three types of glass headed pins: - these ultra-fine pins, diametre 0.40mm – length 36mm, - extra-fine pins, diametre 0.60mm – length 30mm, - picot pins, diametre 0.80mm – length 48mm.
