This is the Cybex child seat base, BASE G. It is compatible with CLOUD G i-SIZE and SIRONA G i-SIZE. It is new, unused, and has been stored at home. 【Brand】Cybex 【Model】BASE G 【Compatible Models】CLOUD G i-SIZE / SIRONA G i-SIZE 【Condition】Unused Thank you for viewing. Purchased online on October 11, 2025, and delivered on October 17, 2025. I mistakenly purchased the wrong type and it was not compatible with the child seat I already had, so I am selling it. I opened the box and bag to try to fit it to the child seat. I spent about 1 to 1.5 hours trying to fit it to the incompatible child seat. It will be shipped in the original Cybex cardboard box. Retail price: 29,700 yen (tax included) I will ship it as soon as possible, usually the same day or within one day. I am also listing it on other sites, so please leave a comment before purchasing.
