You're looking at 10 meters (11 yards) of highly smooth, waxed, extremely heavy duty brown woven polyester thread for leathercraft.
This non-stretchable 1mm (0.04 inches) thick thread has been woven from dozens of micro fibres and will provide smooth and consistent stitching for wallets, bag, saddles, etc., and, unlike linen thread, will not rot.
This amazing thread can easily support 12 kilograms (24 lbs.) with a single strand, making it much stronger than linen thread, but will not stretch like other synthetic threads! Comes in a variety of colours, including black, brown, dark brown and natural leather. This 1mm thread is designed for the toughest of applications where strength and durability is a must, such as saddles or large bags. Large holes to accommodate this thread are recommended when stitching.
0.6mm thread is also available for more delicate work, such as watch straps or miniature handicraft, and 0.8mm thread is available for most applications.
