Thank you for viewing. Brand new, unused. Stored at home. I only checked if the power turns on. Recommended for this time of year as it gets warm. Relax Loop Neck Care Relaxation Neck Warmer Shoulder Neck Neck with Thermal Mode Compact Discreet Wireless Rechargeable Lightweight 【9 Levels, 4 Modes of EMS】 You can select from 4 types of EMS stimulation patterns. The sensation of EMS varies depending on the mode, allowing you to choose the mode that suits you, or change the mode depending on your mood. The intensity of the EMS current can be selected from 9 levels! If you are a beginner, please try starting from 1. You can feel the EMS sufficiently at around 1-5. Around 6-9 is a fairly strong stimulation. Please adjust to your preferred strength. 【4 Levels of Thermal Mode】 A heater is built into the electrode pad, warming your neck. You can change the temperature from 1 to 4 as you like. It gently warms your whole body from your neck. The EMS mode and thermal mode can be turned ON/OFF separately, so you can use "EMS + Thermal", "EMS only", or "Thermal only". 【Compact Design】 Necklace-type shape, compact + lightweight, you can use it with little feeling of wearing it. Weighing only 57g, it can be worn discreetly under the collar or clothes and is not easily visible from the outside. You can use it without worrying about others' eyes, not only during relaxation time at home, but also in the office or when you go out.
