The 1000m length, I do the spools myself, with a bobbing winder machine, I have tested how they come out to use in the sewing machine and there are no problems at all. .
The 350m per reel, is ideal for domestic machines, these are 10 reels in total 3500m but you can mix the colour to make 10 reels
The second picture in the main photos is one of them, this is how will come to you if you buy 1000m
Probably you can buy similar ones cheaper but not the same quality.
Just for the records, I have been using this thread for over 15 years in my workshop, it never gives me any problems.
The sample is about 5 m, don't expect to do much with it, just enough to see the colour and quality.
Polyester Thread – is an all-purpose sewing thread for sewing on knits or woven of synthetic or natural fibres or blends where extra strength is required. The polyester gives strength and elasticity heat resistant surface. This thread requires a slightly larger needle, . Threads are lubricated and polished to give a smooth surface combining the strength gives good resistance to weak alkalis and degradation by UV light.
Recommended for upholstery, garment, household textiles and overclocking, can be used for leather but I recommend to use the M 27.
