■ Polban Advance The hip seat was only used a few times. Neither the child nor I found it to be a good fit. Color: Ice Gray Retail Price: ¥11,000 (tax included) Includes a single shoulder belt. Retail Price: ¥2,750 (tax included) ≪Target Age≫ From when the baby can sit up (around 7 months) to 36 months (approx. 15kg) ■ Lucky Industry Rakupa ※ Similar to Polban GO, but this model from the same brand does not have a belt closure. The sling was also used a few times. Color: Beige Retail Price: ¥5,498 (tax included) ≪Target Age≫ From infancy when the baby can sit up (around 7 months) to 48 months (20kg) (Facing-in carry up to 24 months) ※ Individual differences in physique and weight may vary even within the same age range, depending on the child's development. Neither item has any noticeable damage. No boxes or instruction manuals. Will be shipped together in another box. If sold separately, I'm considering ¥9,500 for the hip seat + shoulder belt, and ¥1,500 for the sling.
