[Contents] Main unit x 1, Head x 1 [Size] Approximately 18.5 x 3 cm [Weight] Approximately 71g [Battery] 1 AA battery *Instruction manual included (English) [How to Use] When the tip of the pen is lightly applied to the skin, a pulse of electricity is generated. 9 modes can be selected. Choose your preferred intensity mode based on the sensation of stimulation on your skin and pressure points. (Test the stimulation with a weaker mode before use.) Applying the massager head lightly will help the pulse electricity penetrate more easily. [Important Notes] ● The effects of use vary from person to person. ● You may feel electricity in the handle if using a stronger mode or if your hands are wet, but this is not a malfunction. ● Due to being an overseas product, there may be some minor scratches or stains. Please confirm and understand this before purchasing.
