A BLIND SPOT MIRROR WORN LIKE A WATCH. I DESIGNED THIS OUT OF MY OWN CYCLING FRUSTRATION. IT PROVIDES SAFETY TO THE CYCLIST FROM ANY ONCOMING VEHICLES. YOU DO NOT HAVE TO TURN PHYSICALLY WHEN LOOKING FOR TRAFFIC [SAFETY FROM BICYCLE VEERING]. MADE FROM RECYCLED FABRIC AND METAL RINGS.THE MIRROR WAS PURCHASED AS A CAR BLIND-SPOT MIRROR.I HAD TO PRY THE MIRROR FROM THE HOUSING AND DRILL SMALL HOLES TO ENABLE IT TO BE ATTACHED TO THE FABRIC.[VELCRO OR TWO RINGS CAN BE USED FOR SECURING STRAP ].I FIND IT INCREDIBLY USEFUL AND PRACTICAL. IT IS SAFER IF TRANSPORTING LARGE LOADS AS THE NEED TO LOOK BACKWARDS IS GREATLY REDUCED. [also comes in handy for checking out yourself or what's going on elsewhere. ie;strangers,police etc]
