I’m sure you recollect seeing Braille staplers and dispensers here on YD. What we have today is the Braille Tape; I think it’s the simplest and most functional of them all. It’s just a sticky tape with parallel dots that you can hand punch to write a Braille message. Label bottles or mark out the danger zone, do it in a jiffy.
