These high-quality Japanese pins are a product of true attention to detail. The nickel plated steel pins are polished lengthwise to ensure smooth fabric piercing, and the pink and lavender glass ball heads won't melt when ironed. At 0.5 mm thick and 35 mm long, these pins are great for tacking thin fabric or for detailed work. Akari Glass-Head Pins, 20 pieces, by Hiroshima from Tulip Corporation of Japan.
