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. It's a slim backpack for everyday use, but when you have more luggage, you can expand the gusset to make it about 1.5 times larger. I usually use it as a smart commuter backpack, and when I'm on a business trip or traveling, I can expand the gusset to carry luggage for 2-3 nights. There is a large main room for clothing and travel supplies, a room with pockets for documents and gadgets, and a room for PCs and tablets. The gusset can be expanded to approximately 9cm, and although it usually has a slim shape, when you have a lot of luggage, you can greatly expand the main clothing and travel supplies room. Capacity is approximately 1.5 times larger by expanding the gusset! The storage capacity has been significantly increased from 21 liters to 32 liters. The main clothing/travel supplies room is fully open, similar to a suitcase/carry bag. Mesh partitions and cross belts prevent cargo from collapsing, making it convenient to see what's inside. The computer/tablet room can store laptops up to 16 inches, tablets up to 12.9 inches, and documents. Protect your equipment with belts and cushions that prevent it from accidentally popping out. There is a front pocket on the front side of the bag, making it convenient for you to quickly take out small items. The document/gadget room has 3 pockets for small items, 2 mesh pockets, and 2 pen pockets, for a total of 7 storage areas. With a depth of approximately 7cm, it is ideal for storing thick documents, catalogs, and A4 files. *The accessory pocket (top) can fit an iPad Pro 12.9 inches, but the bottom is shallow so about half of it sticks out. You can comfortably carry it on your back with its highly breathable mesh fabric and cushioning material. It has a simple design with no decorations and is available in black and can be used both on and off, making it perfect as a business bag or school bag. The fabric is water-repellent, so you don't have to worry about it getting wet or sudden rain. *The zipper part is not waterproof. During heavy rain, water may seep through the zipper. It has a handle that allows you to carry it in your hand, either vertically or horizontally. Comes with a carry supporter that can be attached to a carry case. The shoulder strap is retractable, so it won't get in the way when you carry it with just the handle or use a carry supporter. ■Warranty period: Initial defects only Sanwa Sanwa Sanwa Supply waterproof business bag popular business bag 15.6 pc bag pc bag thin business trip bag overnight men's 3way business trip business bag backpack backpack computer commuting backpack for commuting business backpack extensions laptop back pack 3-way bag popular 3-way bag business ranking popular business backpack ranking commuting backpack that won't lose its shape computer backpack pc backpack backpack that fits A4 size 3-way bag men's rucksack casual business backpack popular commuting backpack ranking carry-on carry-on allowed carry-on compatible popular 2 night 3 day bag ranking carry-on bag
