I only used the bed and mattress when I was at my parents' house during the newborn period. The other items were only washed and never used. I used it for about 2 months, but I didn't use it very much. There were no leaks or spit-ups here. I found it easy to change diapers during naptime by opening the foot area. I think it's in generally clean condition because I used a bath towel when putting the baby to sleep. However, the comforter was only washed and not used, but there were faint spots on the back. Please check the 5th photo. Since this is a layman's inspection, there may be oversights. Please only purchase if you understand. The original price was 8,580 yen at Birthday. Please check the 4th photo for the size. All set contents are included. I plan to ship it in a bag or wrapped in bubble wrap. I am also selling other baby items. If the shipping cost doesn't change, I'm happy to combine purchases. I may compress the items for shipping due to shipping costs. Price reductions are also possible. Please consult in the comments. Thank you for looking.
