【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. 💡 [Designed to reduce the strain on your wrists and arms] There is no need to move the mouse, so the design minimizes the strain on your wrists and arms. When you use a mouse for a long time, you may feel pain in your wrists and shoulders, right? We highly recommend a trackball mouse that reduces fatigue and takes up less space. The EWIN trackball allows you to operate the cursor by rolling the ball with your thumb. It also has an ergonomic shape that fits comfortably in your hand, ensuring comfortable operation. A perfect solution for those who feel strained wrists and shoulders. Please try the EWIN trackball to reduce your burden while working efficiently and comfortably. 🌟 [Equipped with a variety of button functions] The trackball mouse is highly comfortable and easy to use, and in addition to the left and right buttons and wheel, it is equipped with a DPI button that allows you to change the count depending on how you use it. This DPI button allows you to switch the cursor speed in 5 steps: 200 counts, 400 counts, 800 counts, 1200 counts, and 1600 counts. This allows you to easily perform everything from detailed work such as Excel and drawing to work that uses a wide screen.
