In April 1997 a promotional, rainbow-framed card featuring Red with the four starter Pokémon (including Pikachu) was released in Ito-Yokado stores in Japan. A few cards also have Holofoil backgrounds on the front, as opposed to the usual non-holofoil, pixelated background. The backs of the cards provide simple information about the featured Pokémon, usually their evolution families and what level they evolve at. Much of the artwork featured is exclusive to this series. Part 3 & 4 (1997) depict a Pokémon using a move it can learn by leveling up, such as a signature move or a move that it is particularly associated with (Images available below). 12 Prism (Holo) cards were available in this set, including Mew & Mewtwo. The back of the cards provide information about the Pokemon Statistics, and also details the 1995 copyright, along with 1996 Made in Japan, Bandai.

The front of the standard cards of Part 1 & Part 2 were primitive in their appearance, as the artwork was early in its creation, and feature the words 'Monsters Collection' emblazoned along the base of the card and 'Pocket Monster' and card number at the top front of the card. These secret cards are promotional cards that were distributed at Ito-Yokado department stores.

In Part 3 & 4 (1997), the total amount of cards was reduced, but it has two secret cards. Part 1 & 2 have 309 cards in total and more varieties than other Carddass sets.

They were sold in sets of 5 cards for ¥100 or one card for ¥20. The first Pokemon Carddass sets were released in September 1996 by the Japanese toy making company Bandai.
