5PCS Magnetic Seam Guide and Sewing Rolled Hem Presser Foot Set, Sewing Machine Magnetic Hemmer Guide and 7/8/ 9/10 mm Sewing Rolled Hemmer Foot, Sewing Supplies for Brother Singer Sewing Machine

The seam guider worked perfectly and has a very strong magnet. It will not budge at all. My main issues were with the hem roller. I found it difficult to use. I felt like the fabric didn't feed through the rolled part very smoothly and would come out often when using. It also came out a little uneven. Not that much but I did notice. Also thicker fabrics have a harder time going through like when you get a thicker part from the seam of a different section. Overall I don't know if the roller is worth using.

All of the hem rollers are sturdily made. The seam guide is also well made, and easy to use and adjust. No issues.
