Kreinik Japan Threads are synthetic, non-tarnishing gimps available in gold, dark gold, silver and copper that give the appearance of stitching with real metals. Since real metal threads are rare and expensive, Japan Threads are an ideal substitute. Available in Super Fine #1 (thin), Fine #5, and Medium #7 (the thickest).
