In case your bike breaks down as you're riding, it'd probably be good to have the Mopha Tool Roll on hand if you've got a couple of instruments you like to carry around with you.
The Mopha Tool Roll is designed by ehworks who decided to ditch the rugged boxiness of toolboxes for something that's a lot easier to work with. The item is made of waxed canvas with a leather trim. Your utensils are secured by a stylish leather toe strap with a buckle on the end. The interior has 10 small compartments of varying sizes for items you may want to store on the way out. It doesn't even have to be bike tools, you can store other types of items as you please and it'll work just as well.
