Sharp single-edged cutting blade. Please only use these nippers for cutting plastic (PS resin, PP resin, ABS resin, and PE resin) 3mm and less.
Transparent/translucent PS resin is hard and is not recommended to cut more than 1mm.
Don't use excessive force when cutting. Cut as close to center of the blade as possible.
Do not twist the blade while cutting or during releasing the blade. Do not cut if it doesn't fit within the length of the blade.
