Thank you for viewing. This is the Workman 2025 model Peltier vest. I purchased it in July 2025. I used it about twice, but I stopped using it because the device wasn't working well. The device was then replaced with a new one due to a defect. Since I bought something else in the meantime, I have no opportunity to use this, so I am selling it. The vest itself has been used very little, but the box was in poor condition from the time of purchase. Please understand that this is a used item, including the condition of the box, before purchasing. * All accessories are included. * Operation has been confirmed.
