There are at least 4 different types of licensed FFVII model kits.

The Cloud and Aerith model kits were made by Bandai in 1996. They came in boxes including platic parts, instructions and little stickers for eyes. There are also fake version of these model kits, for more information see "Fakes" section.

The Cloud & Daytona model kit by Kotobukiya is a rare and valuable item.

There are most likely more model kits of this series, but I have only one picture: Tifa.

 Additionally there are some limited winter edition model kits, but I only have pictures of Aerith and Yuffie. These model kits are made of clear plastic and come with an individually numbered authentication card.

There are also A LOT of fake and unlicensed FFVII model kits. For more information please see the “Fakes” sections for more information.
