I purchased this item in excellent condition on Mercari in May 2024 and used it for about a month. Operation was confirmed at the time of listing (October 2024). ※Seller's description at the time of purchase (excerpt): Purchased new in September 2023. Used for about 3 and a half months from the newborn period until the baby started rolling over, and then stored. I believe it is in excellent condition as I intended to resell it, but please understand that it is not unused. ※I also used it with the intention of reselling it, so please purchase it if you understand that it has been in the hands of two people. ※Simple packaging with bubble wrap around the outer box. Please understand that the box may be crushed during shipping. ※Requires 3 AA batteries, but they are not included, so please prepare them. I am also listing other baby items. Please contact me via message if you would like to purchase multiple items. #Baby Alarm
