Stainless steel pins, for pedicure services, for podiatry for ingrown nails treatment. The super gel glue is placed on the rough part at the bottom of the base of the pin. Then place the pins on the nail, 3mm away from the skin, in a perpendicular position from one to the other. Allow the glue to dry for 2 to 3 minutes, then place the end of the plasticized clamp chain on one of the stainless steel pins and stretch the elastic - so that it is tight - and place it on the second pin. Cut the excess rubber band with scissors. Each pin has a diameter of 3.5 mm and a height of 2 mm. Mossi Epil.
