pbb&o A4 red felt document brief case bag

I don’t know this brand and couldn’t find much on it other than it might be registered in Hong Kong, though the bag doesn’t say where it’s made. The bag is gorgeous. Thick, dark red felt fabric with detailed stitching on edges and seams (note photo of one small missing part of that stitching which still has the thread attached and could easily be repaired). Fits A4 size documents (210 x297 mm) and many other papers or objects, of course. Outside dimensions are 13 x 11-1/4 x 4 inches. Really unique and special.
