'Tanzaku' - 5 Ribbons = 1 point
Tanzaku (短冊) or Tan is the basic Ribbon hand (ergo consisting of Ribbons that don't make Aka-Tan or Ao-Tan) in Koi-Koi. Tanzaku are small vertical poem cards, approximately 36cm long x 6cm wide that may be plain or decorated with coloured designs, sprinkled with cut gold, silver or mica or covered with silk. The Japanese write wishes on them and hang them in trees. Supposedly these originated from small slips of paper used for divining in ancient times.
