Purchased in July 2025 and sent to my son. However, he never used it, and the sticker is still on the plate, so I am putting it up for sale. I bought this item because it is excellent and the plate was praised for its high cooling capacity. However, my son seems to be wearing an inexpensive vest he bought himself. When storing it, I lost the parts that secure the plate. These parts are for the back, so I think they would be difficult to come off. It's still hot. Since it's without a box and parts, I'll sell it at a lower price. Please consider it soon.
