Hey kitty, my nail in for my oil dome actually did break. Guess I got it too hot. Think u can make me a few? Here's the link to a glass nail for an 18mm bubbler:

It says in the description that the thickness is 5mm and it will fit all 18mm male joints.
Also, there nails are pretty pricey, I don't understand why, they loook so easy to make, but they have quartz nails that are 20$. What's the benefit of quartz? Will it not break from heat'? Cuz I may just buy one of those.
Do u work with quartz?
