Dr. Grabow pipes are commonly available at Drugstores such as CVS, Walgreens, and Rite-Aid, and forego any expensive and/or fancy packaging; pipes are sold in a plastic blister pack. Pipes can also be purchased directly from the manufacturer, and customers are invited to take a tour of their factory in Sparta, Ashe County, North Carolina, and purchase pipes directly from the factory. The Sparta, North Carolina factory produces over 200,000 - 350,000 pipes annually, making it the largest manufacturer of pipes under one roof, and it employs 62 people as Sparta's single largest employer. All Dr. Grabow pipes use and accept a 6mm filter; they've been around for a long time and are an outstanding value. Dr Grabow pipes come “pre-smoked” that is to say that they need no breaking in and are ready for your use from the first puff. They come in a wide variety of styles within the separate finishes/lines.
