An appliance for drawing lines has a space enough for one ruler to be inserted in the center, and a ruler, having holes at each one centimeter for small ball point pens to be inserted, is covered by a ruler cover. The ruler cover is made of rubber material to be elastic, and has small grooves at each one centimeter gap for inserting small ball point pens. The appliance for drawing lines includes a reusable paper fixing part inserted to the hollow space of the ruler for fixing the reusable paper in order to accurately draw lines, while having the holes for inserting ball point pens perforated at each one centimeter gap; and small five-centimeter-long ball point pens containing ink through the holes perforated at each one-centimeter interval on the ruler, the grooves perforated at each one-centimeter gap on the bottom of the ruler cover, and the holes perforated at each one-centimeter gap on the reusable paper fixing part. |
