The title goes for the customer service at T.A.G as well as this masterpiece. Crafted to endure wear and tear as well as extreme heat (I use a butane torch) with minimum notice. I believe the piece itself is made with borosilicate glass, however I have been looking for a definite answer to no avail. Although it does exhibit all the signs. Composition aside (impressive as it is), this monster topping in just under 2 ft. Has a pull as smooth as silk. That will leave even the most avid connoisseur satisfied with minimal use. Although the experience and hit deliveries results are so astounding that it will keep you yearning to use it constantly. The minimalistic style yet ferocious functionality make it the talking point of any occasion I bring it out for. The shipping was exceptionally fast and discreet on T.A.G's end, and customer service is more than courteous and professional (even when met with unwarranted adversity). Do yourself a huge favor and start and end your search with T.A.G first for any glassware needs before getting overcharged by local shops for second hand glass or even other online glass shops you will not regret it.
TLDR:: price= phenomenal.
Customer service = phenomenal
Most important the piece itself = phenomenal
Overall far above and beyond on all expectations
