This is a popular child seat. I used it from around 1 month old, attaching it to a stroller (Libelle). It was very helpful for walks, and although it's heavy, it was also useful indoors and when eating out. I will also include the adapter that attaches to the Libelle. You can also use it as a child seat if you purchase the Base T separately. ⚫︎Reference Age: Newborn to around 18 months old ⚫︎Usage Criteria: Height 45cm to 87cm Original price: 44,000 yen (tax included) There are some minor scratches on the plastic parts. Please check the photos. It has been home cleaned as much as possible. Since it's large, I will prioritize those who can pick it up in person. Please consult with me about the general location for pick-up before purchasing! (Those who can pick up around Yokohama City, Yamato City, Fujisawa City, and Ayase City, Kanagawa Prefecture are preferred ◎) I am relatively flexible with the date and time! *I will discount 3000 yen if you pick it up in person.
