The Tri-Dot Glass pipe is an affordable piece that packs great performance in a pocket friendly size. This product has been constructed in America using lab grade durable glass commonly refereed to as borosilicate. This means that this product will not easily get damaged if you were to accidentally drop it. Also, the glass blowers have implemented three marbles, thus the name, which is meant to be an addition to the pipes overall design. In order to increase the stability of the pipe when it's on a flat surface the glass blowers have also flattened the bottom of the bowl. This is a great feature because it is another measure found in this piece to ensure it doesn't accidentally fall.
