"I unfortunately have to live with several pairs of spectacles with different lenses and in spite of the frames costing an arm and a leg the supplied cases are rubbish. These bullet cases are strong, as compact as they can be and very easy to live with as they fit into trouser pockets, car storage bins etc. being different colours it makes identifying the right glasses easier. I have bought two and will be buying more as they are useful for organising the other odds and ends that live in one's pockets. They are inexpensive and when ordered on Friday morning arrived with Saturday' post. The whole process being tracked with emails. An excellent product and excellent service."
