This is a plate carrier made by Worker Kit. I've used it three times after purchasing it here, for a total of six times. I washed it every time after use, so it's clean. I think it's a rare item that's not often seen in Japan. The plate carrier comes with anti-sweat pads inside and a backpack. I'll also include brand new, unused pads. And as a bonus, I'll include simulated bulletproof plates, also known as "beat boards"! Please feel free to ask any questions in the comments. Thank you. I will be away for work starting tomorrow, so I will be unable to ship until Monday, October 20th!
