These indicators help people who are blind or visually impaired identify and differentiate between common feeling household objects like:
-shampoo & conditioner
-debit & credit cards
-cans of food
Each indicator has a condensed cell representing numbers 0 to 9 in braille with a bar for orientation to make sure numbers do not get disorientated.
The squares are 0.5 inch so I used and 0.5 inch double sided adhesive to stick the identifiers to items.
