Our new Print Braille Ruler solves both these issues. First, it's made of a bendable, plastic material, meaning your new ruler is flexible enough to measure around angles but strong enough that it won't break with use. Tactile markings insure an accurate measurement, even up to 1/8 of an inch. Last but not least, the ruler sports both raised Braille and large print numbers, so everyone will be able to use it without counting lines and guessing at results.
