ChildBrite's new Braille Chips for the Sighted will provide the perfect tool to help your students appreciate the challenges faced daily by those who are blind. The National Foundation for the Blind states " The real problem with blindness is a lack of understanding and information" . ChildBrite wants to help change that by introducing this accessory for their new Sensory Center. Made in the USA of a high impact, durable, non-toxic resin, these chips include raised alphabet, numeric and punctuation mark images on the top half with the corresponding Braille symbols on the bottom half. With this 44-piece set children, teens and adults can learn that blindness does not have to come between them and their goals in life. Let's Educate.Each piece measures 2.5" x 1" x .25" and passes the standard choke test.
