This is a mosquito net for the BABYZEN YOYO 0+ stroller. Retail price: ¥4,400 I purchased this but didn't use it, so it has been opened, but the item itself is unused. I did attach it to the stroller once, so please understand. Also, I will not include the box when shipping, but I can include it if you don't mind it being folded in half, so please let me know when you purchase it. If you have any other questions or concerns, please feel free to comment. - Brand: BABYZEN - Model Name: YOYO 0+ Mosquito Net
