Re: HOOKAH VASE FOR KM 1001 DOUBLE DECKER.
I know Social Smoke has a few rounded pyramid style bases that could potentially fit, but their openings are 1.875". Large KMs, like the 1001 double decker, tend fit into a 1.75" opening, so you could run into some issues there with the stock grommet. Also, Sahara Smoke has a lot of large bases that have 1.75" openings. None are quite a pyramid style, but I have one with a wide bottom and it's fantastic.
I don't own anything cos you guys bought everything!
