Superior Marker Company was started in 1921 and manufactures a unique chalk that is made with Ultra Marine Blue pigment and other materials.

The chalk is unique because it is soft enough to write on the delicate pages of the Bible, without harming them, and is also completely erasable with a fabric eraser, or soft cloth. The chalk can also be used for "take-off" work on Blueprints, by Builder's and Architects and is sold to the San Francisco and Sacramento, CA Builder's Exchanges.Besides,it is narrow and fits into a chalk holder so that writing with the chalk is easy and convenient.Our main customers are Christian Science Reading Rooms, worldwide, as well as Builder's Exchanges in California.In 2009, The new product will be introduced to Christian bookstores, both denominational and non-denominational, as well as Seminaries, Bible Colleges and Universities, throughout the United States, and soon after "Erase-A-Mark" will be introduced to similar markets around the world.
