Thank you for viewing. Aramid Fiber Case for Apple Watch Series SE / Series 6 / 5 / 4 40mm "DURO" is a special case series from Deff. Its main material is "aramid fiber," which is five times stronger than steel of the same mass and half the weight of glass fiber. Among these, it luxuriously uses Kevlar(R) made by DuPont, a world-leading brand in the United States. This product boasts a thinness of approximately 0.6mm and a light weight of approximately 0.6g (for 41mm) that doesn't make you feel the size of the case. The case is designed for a perfect fit that does not use any double-sided tape or adhesive, and red Kevlar is used on the back as an accent. Also, you can charge the watch with the case on. https://www.shop-deff.com/c/aw/awse/DCS-AWSED #deff #ディーフ #duro #アラミド #ケブラー #applewatch #アップルウォッチ
