Here's the perfect item for heatstroke prevention! This is a set of 3 brand new, unused PITA-BARRIER COOL products, designed to keep the inside of your hat cool. Although there are traces of price tag stickers having been removed, please rest assured that these are new, unopened items. Each one retails for over 2,000 yen, so this is a great deal. PITA-BARRIER COOL 3-piece set, for caps, hats, cooling, sports, and heatstroke prevention. I have many available. Bulk sales are possible.
