A heavy-duty device – the Bong 7.0, the ROOR bong with the thickest wall diameter of all the pieces of our collection.

7 mm wall thickness – that means 40 \% more glass volume compared to the models with 5 mm, a fact that results in an unmatched grade of stability.

We also offer an Icemaster with this wall thickness. Through the extreme weight these pipes are especially firm in your hand.
