This is a brand new leather work bag from The Eighth designer range at Debenhams.  It comes with the sales and authenticity tags attached. The full retail price is £140.  The details are as listed below.  
These are some minor indents in the leather caused by other bags pressing against this bag while on shop display. These are pressure marks only - the leather is intact - and they are not obvious so the bag retains its attractive appearance.
