Tulip Glass-Head Pins, tube of 20 pins. These pins are great for tacking thin fabrics or for detailed work and the glass heads are heat-resistant. Nickel-plated steel shafts, .50mm thick, 35 mm. long. Like our Tulip Needles, these pins are manufactured in Hiroshima, Japan, and are designed with precision points. Special processing produces a body of ideal strength; the nickel-plating means these pins resist rust and glide easily through fabric.
