Thank you for viewing! ✨ Just insert it inside your hat! ● How to use: As shown in the image, insert the non-woven fabric side towards your head into the folded-over part of the inside of your hat. For hats without a fold or to prevent slippage, you can also attach the non-woven fabric side to the hat with the enclosed tape, etc., and secure it. You can also cut the product with scissors to fit your hat. This product does not guarantee the prevention of heatstroke. ● Handling: When dirty, wipe it with a wet wipe, etc. The gloss of the aluminum surface maintains its performance. When wet with sweat, dry it in the sun. The silica gel inside regenerates the quick-drying, deodorizing, and dehumidifying functions repeatedly.
