Thank you for viewing! This is a warm water cotton wipe system. It heats water using a power outlet. It has been used, but I believe it has been kept relatively clean. I've heard that with warm wipe warmers, the wipes can dry out from the heat when the number of wipes is low. However, with this system, you warm the water and apply it to the cotton each time you use it. This way, you don't waste cotton, and it's gentler on the baby's skin than wipes. My personal experience is that even on cold winter days or when changing diapers in the middle of the night, I was able to use it without waking or upsetting the sleeping baby with a "cold" shock. Also, because cotton is gentler on a baby's delicate skin than wipes, there were no rashes or skin problems. I also found that cotton is much more cost-effective than wipes. This does not include cotton. You can purchase two sizes of cotton at baby supply stores and use whichever you prefer. It will be shipped in the original box, and will be simply wrapped in plastic to prevent it from getting wet. ----------------------------------- This is my first Mercari listing in three years. Most items are used, and the condition of the items is based on my personal judgment, so I would appreciate it if you could purchase them with understanding. I strive for prompt shipping, but as I am raising a child, I have set the shipping time to "4-7 days" to account for the possibility of delays in responding to comments or shipping items. I usually ship relatively quickly if there are no issues, so I will try to ship as soon as possible.
