Kyosho has 2 different lines for 1:64 scale.
The first is called Beads Collection which is a high-end line ceased production a couple of years ago. The details of the models are very fine and retail prices are around US$20. These have now become rare collector items since they are no longer available in the general market.
The second line is called the Sunkus K Collection which is still in production and hugely popular worldwide. These models are sold exclusively in Japan in the Sunkus K store and have become quite hard-to-find model as they are often sold out instantly.
Over 50 different series have been produced (average one new series introduced every
1-2 months). Almost all models come in a "blind box" where you don't know
what is inside until you open the box - a common aspect for Japanese
toys. Some of the recent series include a "secret model" (eg. treasure
hunt) which is extremely rare.
