this bag has been used quite a lot but still has got a lot of life left in it yet. there are no stains of pen marks inside. the only issue is that I have changed the monkey as the previous one got damaged and the key chain on this one is darker. one main compartment and back zip pocket and a front velcro fastening pocket there is also a velcro fastening pocket at each side of the bag. the bag is grey with a cream background so it gives a yellow tinge but that is how it is. it isn't white. 12 inches wide 18 inches in height and 4 inches deep.
