This is a slim-design ROCKBROS top tube bag, black in color. I've used it about twice. The bag itself is good, but I'm selling it because it doesn't suit my needs. - Brand: ROCKBROS - Color: Black - Type: Top tube bag Capacity is 0.6L, and the size is 20*8.5*5.5cm. - Design: Slim shape, and the opening is magnetic for easy opening and closing. Also, the dial-tightening type takes a little getting used to, but it didn't slip, which was good. Thank you for looking.
