Using this Torvol TO034 Modular Organiser Case is a breeze. First, collect all your cables, wires, and other spare parts. Then, put them into the 4 mesh pockets for easy storage. To attach the case to your Urban Carrier Backpack, use the MOLLE system on the side of the backpack. Just line up the attachment points and secure it firmly. When it comes to maintenance, it's simple. You can use a damp cloth to wipe the case clean if it gets dirty. Avoid using harsh chemicals as they may damage the material. Also, make sure not to overstuff the case as it may affect its functionality and the MOLLE attachment. If you need to carry more items, consider using another similar case or upgrading your backpack.
