• The official HR badge of Hokutoryu ju-jutsu.
• Attaching to the jujutsu suit by sewing or "pressing"

A tip for "pressing" the fastening, place the marker in place with e.g. a pin and
put a piece of baking paper over the mark, then use the iron at full power for 30 seconds.
Pressing with a small movement, repeat the same on the wrong side of the suit but without baking paper.
If the marker has not caught on properly, repeat the above instructions.
