Special seamless jersey -free press buttons are especially appropriate for finer fabrics, stretching like baby clothes or children. "Seamless" pressure buttons can be worked either with the vario pliers or the tripod (allows you to lay Pressures far from the edges of the fabric). The better of the jersey-press button is that it does not require drill a hole to be placed: the integrated claw pimples repel the fabric and thus allow it to be damaged. Washing, spinning, cleaning, iron or roller ironing does not pose any problem at Jersey stainless pressure buttons. A installation tool is included in each package. A guide is located on the back of the package. Boast of 10 pressures. Diameter: 10 mm ring. Color: silver.Matière: Brass.
