Five-Grid Cowhide Ball Pattern In-Stock. The latest flap design in lambskin features a classic upgrade, eliminating the previous zipper design that was rough on the hands such a thoughtful change! After being hurt by various zipper bags, I truly love the new flap design of the five-grid style. It has excellent capacity, looks great whether carried by hand or slung across the body. The vintage diamond pattern and timeless bag shape make it a classic that every girl deserves to own. Model 6605, size: 24cm.
