This is our 1/8th inch Highlighted Ruler. Not just another 18 x 6 1/2 inch ruler, it has the 1/8 inch lines highlighted and they run all the way across the ruler so that you will have no problem following them. Have you ever been asked to cut something and 7/8 inch and get upset because you only have three little marks on the ruler to show you the 7/8 inch line. Not with this ruler, there is a mark for the 7/8 in line every 1/4 in. on the ruler so that you can easily follow the line clear across the ruler and always have your strip measure the same on both ends.
