Helluva Boss Stolas Backpacks for Sale | Redbubble。Helluvaboss Young Stolas Pattern Sling Bookbag / Crossbody Backpack- New This is a small cute crossbody Backpack. Please see Pic with measurement, as it is not the same size as a regular large Bookbag. I made the seamless pattern/design myself (took alot of time with a lot of love) and had it printed into a bookbag! Please ask with any questions! (Will take better pics with better lighting soon!)
