This bag is an easy place to store your Dremel 7300 or nail groomer along with the battery. It also offers protection. The Dremel itself and charger are great. There is space for additional grinding wheels, although it would be better if the holes for the grinding wheels were clearly defined. Some seem too superficial. Practical zip compartment. I also ordered a spare battery when I ordered it. Now I understand that the case would be even better if it had room for a spare battery.
