These are two rare rc mini 4wd series. In particular the Junior Kyosho Optima is the super rare item in this package deal. It was purchased at a hobby shop at Nakano mall about 9 years ago. It is incredibly rare to have this new in box, for sale. The Kyosho mini is for collectors who want to place it along its bigger 10 scale brother! If you are an Optima enthusiast this is a great opportunity to have the mini!
