Always try here first!
So sorry to say these are the worst needles (6mm) I have ever used in 70 years of knitting! The points are too long and sharp, easily splitting the yarn - why is there a tiny ridge just below the point? The stitches do not slide along them but have to be pushed every 2 inches or so. They also seem to grate together when making the stitches. One star as they are the correct size. (Had to change to metal needles)
