Please visit the About TRG page for more information on the materials and methods employed in the shaping and finishing of TRG pipes.  If you are unhappy with a pipe for any reason at all, you may return it, unsmoked and in the same condition that you received it, for a full refund within two weeks of your receipt.  Each pipe is also guaranteed against burnout for a period of one year.  Shipping is included in your purchase price, as is a Wyoming mule deer tamper/pick made by my friend Phil McCall of Iowa.  Contact Phil.  Also included is a custom made TRG pipe bag of excellent quality.
