Hello Everyone, I was just playing around with my H bags and accessories this morning and being creative. Then, I noticed that the extra belt/strap that came with my Kelly flat could be used as a shoulder strap for my Kelly briefcase as well. I am so happy of this discovery and wanted to share it with you. The strap measures about 1.5cm in width and can loop thru the metal hooks on a Kelly either the bag or briefcase. Plus, the strap doubles as an adjustable shoulder strap as well given that it has a belt like buckle. Another H accessory, the Orion belt also has the same width and can double as a shoulder strap too. I will be able to enjoy my Kelly briefcase more hands-free since I can now carry her as a shoulder bag. Thanks JPG for coming up with innovative ideas such as the belt strap for the Kelly flat. J.
