If full, dimensions approximately 29 cm high and 44 cm long. 16 cm deep. The shoulder strap has a maximum drop of 38 cm. It's in really good condition with minimal wear and well looked after. Both YKK zips working nicely. No key. The only thing to point out is the extra support to pad your shoulder on strap has tears to one side as per pictures. Coming from a smoke and pet free home.
