Using your Boldric 17 Canvas Roll - Up Knife Bag is easy. First, unroll the bag by opening the easy - snap enclosure handle. Place your knives and cutlery in the 17 pockets provided. You can use the zippered utility pocket for small items like bottle openers. Put your business cards in the 3 holders and pens or markers in the loops. When you're done, roll it up and snap the handle closed. Then, use the adjustable shoulder strap to carry it around. As for maintenance, keep the bag dry. If it gets dirty, you can gently wipe it with a damp cloth. Avoid using harsh chemicals as they might damage the natural canvas and the water buffalo leather details. Also, be careful not to overstuff the bag to prevent the pockets from getting stretched out.
