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. [Waterproof Material & Seam Allowance Lines and Cut Lines] Unlike regular bags, backpacks require not only practicality but also waterproofness and strength, so we incorporate techniques that other companies do not have, such as thick fabric sewing technology, strength balance, and three-dimensional sewing technology. 【With 2 Types of USB Ports】The backpack with Type-C and USB ports can use the built-in charging port to charge portable electronic devices such as smartphones and tablets. It is very convenient because there is no need to take out the charging cable and it can be charged without an external power source. You can change the charging port depending on your mobile electronic device. [Design with variable storage capacity] Size (cm): Approx. 32*16*45 (L*W*H).
