Ritza 25, widely known as “Tiger thread,” is world-renowned among professional leather crafters for its unmatched strength and durability. Produced by Julius Koch in Germany, this 100% polyester thread is braided and lightly waxed, making it specifically designed for hand sewing.
Key Features:
-
Flat Profile: Unlike round threads, it lays flat against the leather, creating a clean, decorative, and professional stitch line.
-
Superior Strength: Braided construction ensures it won’t stretch, fray, or break under tension.
-
UV & Wear Resistant: Ideal for high-end leather goods, saddlery, and outdoor gear.
-
Easy to Work With: The light wax coating allows for smooth passage through leather without leaving a sticky residue.
