This patented writing paper designed to improve legibility, was developed by occupational therapists specializing in handwriting remediation. All sheets, front and back, are printed with innovative cues for impacting proper spacing between letters and words, and for regulating letter size and letter alignment on the lines. There are even green & red colored margins lines to indicate on which side of the paper to start the writing line and where to stop. Try a 48-page pack of refill notebook paper and watch legibility improve immediately. Also helps with number alignment for math problems.
