This tool roll is made from oilcloth with a nylon ripstop lining. It's durable and water resistant, and measures 7" x 16". Four pockets will hold all your basics, and the flap keeps everything tucked securely into place. It fastens closed with a new toe strap.
There's plenty of room for your multi-tool, a spare inner tube, tire lever, CO2 cartridge, or what have you. (I always make sure to have snacks in mine.)
(Tools not included.)
This item is already made, and just waiting to be shipped off into a life of usefulness.
