Treat the earth well!! “iPhone Horn Stand” – invented by Bone’s creative minds and made of high-quality material – reflects and enlarges sound without being plugged in. Whether straightening up or swaying your iPhone, it doesn’t hinder communication or charging. You won’t be interrupted when working, exercising or eating, but instead will be able to use the iPhone more freely. We used the mold releasing feature of silicon material to achieve the streamlined shape. You can easily assemble the “iPhone Horn Stand” with the single silicon piece provided only, without requiring any gluing or screwing. We are committed to reducing raw material consumption and saving energy resources through green manufacturing.
