I purchased this MOUNTDOOR 2 or 3 years ago. I injured my shoulder and can no longer use a sacoche. I thought I might be able to use it someday... I have been storing it in a drawer in my closet. This is a great item for those who like sacoches. ・Approximately 12.9cm x Approximately 22cm ・Bottom gusset approximately 5cm (There may be some errors as I, an amateur, measured it.) ・Two compartments when the zipper is opened ・With key leash ・Semi-transparent Thank you for looking.
