✨Brand new, unused✨ I accidentally purchased this, so I'm offering it to someone who needs it. It was very convenient because it could be connected directly to the stroller from Maxi-Cosi. I also have other clothes, shoes, and miscellaneous goods for sale. →#rinngolife If you purchase multiple items, I will discount 200 yen for every two items.
