A 10cm tactile ruler with braille single cell numbers reading left to right.
- The top long edge has centimetre and half-centimetre ridges, with the half being shorter.
- The bottom long edge has centimetre ridges and small notches to allow accurate placement of pen or stylus.
- The left edge has a raised ridge to indicate the orientation and starting point.
- The braille cells are accurately sized as per international guidelines. They are single cell numbers 1 through 0, or A through J.
Recommend printing at a "fine" level for good ridge and braille definition.
