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. • Color: Black • Power: +1.00 to +3.50 • Weight: Approx. 20.5-30.0g • Accessories: Soft case, suede cleaning cloth Frame size 49□20-165, lens height 42mm (lens width 49mm, bridge width 20mm, temple length 165mm, lens height 42mm) These reading glasses can be worn around the neck when not in use.
