Model: Soft Rubber Pipe Bits
Length: 0.72 in. / 18.33 mm.
Width: 0.52 in. / 13.41 mm.
It has no description of what bite/button sizes it fit, and when I got them they don't fit. I even tried to soak in hot water before putting it on it's still doesn't fit. It may fit yours but it doesn't fit mine
Fit well and protects pipe stems.
The tips I received were too big for the bit. I ordered Brigham tips because I also ordered a Brigham pipe. I was fortunate to still have one from another order. It was a BJ Long.
I was a skeptic but after using them I am hooked these are very comfortable and making my pipe smoking a pleasure.
