Yer I think I would quite like a rubber tip as I have to smoke my pipes when out and about, because the building I live in doesn’t allow smokers… 
So usually I am doing something with my hands, which would make something to bite on really handy. Flippin 'eck and I was just at MySmokingShop again today…oh well guess that’s me there at the weekend too 
Well if you do tend to like a RB mouth piece you can buy in bulk on e-bay for 1/4 that price. search 9mm Black SOFTY Rubber Tobacco smoking Pipe Tip Grips they have 12mm also. I only needed the 12mm on one pipe
@basement_shaman none in the UK, damn this small island. Maybe another trip to the tobacconist will be ok 
They all come from China
Ah :-?
