The initial series of the idol training project "Idol Egg" series of the rare series "Chuboz", which is difficult to obtain and cannot be bought again without resale when it is sold out, is released at once. Currently, the early "Idol Eggs" are a super treasure series that has not been sold or released anywhere. The reason why it's so popular is that all the idols who appear in it are U-15, which is super cute and super radical ... It's a super rare work among Jr idol fans because it's not available at all! The mid-late series after the early stage will also be released! !!
