【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.
Carbon ink uses the pigment carbon black, so it has excellent water resistance and light resistance, and dries easily and is clear. This ink is ideal for permanent preservation of records. However, since it is not water-soluble, it will not dissolve again once it dries, so care must be taken when maintaining it when using it for carbon pens, etc.
