Thanks for the info! What did you do to modify the stem? Did it need to have the slot opened? At the price point you could probably even have someone make a better stem!Undoubtedly a great value pipes,which smoke comparable to my few Dunhills, disclaimer: based on my experience dimensions given on their online site are somewhat inaccurate meaning pipes which I bought from there were a bit shorter length what I was expecting,moreover, be prepared to modify the button part of the stem since that leave something to be desired, also the stem alignment may not always be 100% satisfactory
