【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. ✅ [Wide field of view that won't make your eyes tired] High performance binoculars with a 9.5° wide field of view that won't make your eyes feel tired. ✅ [Bright and clear view] The eyepiece lens has a large outer diameter and full multi-coating technology, so the field of view looks large and bright even in dim light.
