Purdys Chocolatier launched a special new product last Christmas. The new holiday box was so popular that it sold out within hours.

It contained the usual assortment of yummy chocolates. So what made this box of chocolates so special?

It was the packaging. The box was lettered in Braille. So was the insert that tells you which chocolate is which.

What is Braille?

Braille is a system of raised dots. Each pattern of dots stands for a different letter or number. People who are blind or have low vision can read the dots with their fingertips.
