Sewing thread
Under the brand name RITZA, Julius Koch produces a variety of well-documented and well-tested braided sewing threads for the shoe and leather goods industry in a range of colours and constructions. Some are suitable for hand sewing, while others are perfect for machine-sewn articles.
Excellent performance with a beautiful finish
The superior construction of RITZA sewing thread guarantees excellent performance, high resistance, and a beautiful finish. Our threads are made from durable polyester, which is highly resistant to dust and preserves the colour.
Custom-dyed solutions can be developed upon request, subject to our minimum order requirements.
