From official page:

This is a thread that skillfully combines the softness of cotton, the luster of rayon and, the stretch of linen; their three best properties. The tension in non-mercerized cotton allows for the creation of a durable thread that can withstand continued use and is extremely easy to manipulate. The muted luster of rayon comes together in high-quality items. This is a medium thread.
