If you like things that are simple and traditional and you also want a regular sized pipe that takes 6mm filters, then Crown Walnut Polished Filter are for you. Available in an array of classic shapes and arguably the most traditional of finishes, these pipes are large enough to deliver a pretty long smoke, while still using a 6mm (Medico or Dr. Grabow) filter in the 728 and 591 models for a cooler, drier experience. Model 2 takes a 9mm European-style filter but comes with an adapter in the tenon so it can be used as a non-filtered pipe. Best of all, you can pick your own shape and pay a price that's competitive with similar, smaller pipes.
