---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- The "IST" is a thumb-operated trackball that features an ergonomic shape for comfortable operation and incredibly smooth operation. Ergonomic design for a natural, non-gripping grip. Its shape fits comfortably in the hand regardless of hand size or grip style. The angle is designed to reduce strain on the wrist, making it comfortable even during long periods of work. The support unit uses high-performance bearings manufactured by MinebeaMitsumi. Because frictional resistance is reduced, it enables smooth ball control, as if the ball is floating in mid-air. Because it does not rub against the ball surface, less dust accumulates in the support unit, allowing for long-term, maintenance-free use. The support unit is easily removable and can be replaced with bearings, or even artificial rubies. *Replacement bearing units (M-BS10) and artificial ruby units (M-RS10) are sold separately. The ball can be easily removed and replaced through a hole on the back, making maintenance of the ball and internal support unit easy. It features a large 36mm diameter ball that fits comfortably in the thumb, allowing you to move the pointer over a wide area with precision in a single operation. *Replacement ball (M-B10SV) is sold separately.
