These CHERRY cutters are in two sizes (30mm and 40mm) in both forward and reverse images (so 4 cutters in total).  Great combination for a stud and dangle set. The cutters are SHARP with a 0.4mm cut wall and a height of 15mm.  They come packaged in a hang sell bag with care instructions included. Hand made in Townsville. All our materials are sourced from Australian suppliers. The cutters are made from PLA on a 3D printer at my home in Townsville from designs sourced from all over the world. PLA, or Polylactic acid also known as poly(lactic acid) or polylactide (PLA), is a thermoplastic polyester. PLA is economically produced from renewable resources.
