Purchased at the beginning of 2024, the hip seat was used 5 or 6 times. The shoulder belt is new and unused. I intended to sell it after use, so I tried to keep it clean, but please understand that it is a used item. The hip seat has a non-slip surface, so the child can be seated stably, and the belt is sturdy enough that my back didn't hurt, making it very convenient. Maximum weight: 15 kg 7 months to 36 months Retail price: Hip seat: 11,000 yen Shoulder belt: 6,600 yen Feel free to comment with any price negotiations or questions.
