I love this bag but full disclosure…I need a bigger size. This sweetie pie is approx. 9.5”x2”x6”. Strap is adjustable and removable. Chain however is not removable. Snap closure. Two interior pockets. One zipped the other is not. Strap is also not black. It is a very dark blue that appears black in certain lightning. This is the original strap that came with the bag itself. This was not swapped out.
