The Wicked Buddy.

CUTTER 08 BMI will change the face of your city. Equipped with an 8 mm polyester QUICKFLOW Chisel Tip, in combination with a compact size strong plastic barrel, this tool will leave its trace forever and ever, thanks to the special invisible ink which appears only under UV lights, turning into a deep dark brown color.
CUTTER 08 BMI comes filled with 20 ml of BLACK MAGIC INK, for writing without being seen by anyone.
