Cans with braille
Cans all feel the same. They’re mostly the same size, shape, and feel, regardless of what’s actually inside them. Have you ever stopped to think about what problems this must cause if you’re blind? Imagine purchasing what you thought was a refreshing can of coke, opening it up, and discovering that it’s actually beer!
Not only would this come as a shock to your taste buds, but you could end up drinking beer at work, which is never a good look. So the Japanese have addressed this by putting braille on the top of their drinks cans. No accidental drunk blind people on their watch.
