This was the original release of this series. These were all also released individually the same year in cardboard style boxes with different colors. Besides the dinosaurs listed below this set also contained an eraser, keychain, mechnical pencil, and a case.
Kuruntosaurus (クルントサウルス) Compass
Kezurinozaurus (ケズリノザウルス) Pencil sharpener
Chokiranodon (チョキラノドン) Scissors
Stegomejaras (ステゴメジャラス) Tape Measure
I have also seen the set in this style packaging.
