World Reidroc Color: Black. The exterior is adorned with many small beads, giving it a luxurious feel. Size: Height 27cm, Width 51cm, Depth 12cm x 22cm There is a zippered pocket and a non-zippered pocket inside. A4 size will not fit, but there is also depth, so I think a pouch, wallet, 500ml water bottle, towel, handkerchief, etc. will fit comfortably. It has been stored at home, so please only purchase if you understand this.
