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.

✅ [Carefully selected, environmentally friendly, genuine materials] "We want you to use it for a long time." With that thought in mind, we have paid careful attention to the selection of materials. The material used is full-grain shrink leather tanned with vegetable tannins, which is highly durable. Beef is eaten at the Bangladeshi festival Eid. Since it uses cowhide after it has been eaten, it is very environmentally friendly. Since it is not chrome tanned using chemicals, there is no need to worry about environmental pollution. Sheep leather and synthetic leather, which get scratched easily, require a lot of maintenance every time they are used, but due to the characteristics of shrink leather, it hardly changes over time, making it a product that can be used for a long time in business situations.
