These are the first-generation ZHENGTU PRO SERIES boxing gloves, which are now discontinued. The first generation featured a mirror-finish metallic color, and these gloves have a triple color scheme of metallic blue, metallic silver, and white. The surface material is microfiber leather, which is more durable than genuine leather. I've used them for training several times, but there are no tears, odors, or pad deterioration, so I think they can be used without any problems.
