Thank you for viewing. This timer is recommended for people with developmental disabilities and those who have difficulty switching tasks. It has been used, but I believe it is still usable. There may be a slight discrepancy in the 1-2 minute display and sound. For those who don't mind minor imperfections. To prevent leakage, the batteries will be removed before shipping. I will pack it carefully, so if you are looking for one, please consider it.
