I was looking to buy anti pollution mask and searched online for the same. But couldn't decide which one to go for because the one which were looking good didn't have any scientific significance and on the other hand which was approved by lab looks more like operation theatre mask. Fortunately got to know about onroad.co and they were able to fulfill both the demands. I went ahead and ordered on amazon it took 2-3 working day to get it delivered. When I unboxed the packaging for my suprise got hand written note which I really liked. Mask Quality is very good and looks trendy. Overall happy experience keep up the good work guys. KUDOS!!
