Impact resistance, light 11g, ultra-thin 0.7mm, just like using a bare phone
DeFF ® DURO ® adopts advanced 3D three-dimensional molding technology to retain the unique appearance design
of Galaxy S23, and provides the strongest protection through precision cutting. Also the USB-C charging port is also
enlarged to fit most charging cables in the market.
DeFF® DURO® case is made of the world-renowned brand DuPont® Kevlar fiber (commonly known as bulletproof
fiber), with a thickness of about 0.7 mm and an ultra-light weight of about 11 grams. It has excellent impact resistance
and reliably protects Galaxy phones. Exterior surfaces are treated with a scratch-resistant and easy-to-clean matte
multi-coat. It will not cause any reception impact on functions including 4G, 5G data communication, calls, wireless
charging, NFC communication, etc.
Also, DURO® Case can be used with our "HIGH GRADE GLASS for Galaxy S23" ultra-hard protector (sold separately)
for even stronger protection. At the same time, it can also be used with the optional "WIRELESS CHARGING TRAY"
wireless charging tray, which won the German IF International Design Award, to achieve high-speed wireless charging
without a charging cable, up to 15W (※).
※ A corresponding compatible environment is required.




Utilizing the thinness and toughness of Kevlar fiber, the mobile phone case is both light and strong, almost insensitive
to the bare phone. Also, with a special matte coating process, it has not only comfortable feeling but also non-slip
safety insurance.

The camera opening on the back is made to be slightly protruded, so even if the phone is placed face down on a
table, the lens will not directly touch the table.


The entire edge is protected by precise molding technology, and the openings around the USB and microphone
holes are rounded and processed.
