Does not interfere with charging

SYANTO is installed by inserting it into the charging port, and we are particular about its thinness so that it does not interfere with cord charging. You can quickly charge it even when it is attached.

ergonomic smartphone ring

My smartphone feels light

By being able to hold your smartphone without having to hold it, the tension in your hands will be reduced and you will be able to hold your smartphone more comfortably. Also, the center of gravity changes, making the smartphone feel lighter.


inherited genes
