oh i think theyre actually marketed for golf. imo it's because of the increase in popularity of golf in korea recently that made these sun patches blow up. i think theyre overpriced and dont offer more benefits than your usual sunscreen. also, there arent many occasions to wear them. theyre really big and honestly look out of place if youre not golfing or exercising. i think @odilemonod has some instagram stories about this particular topic!
