This raised-line graph paper is a simple yet helpful tool for any high-school or college student. These sheets of tactile graph paper measure 8 1/2 x 11 inches. On each heavy-weight sheet of paper are 20 rows of 15 squares, for a total of 300 beautifully-raised, easily-felt boxes. Each square measures approximately half an inch (1 cm) across and is differentiated by touch with the use of clear raised lines which are as sharp as regular braille dots.
