In my experience, it depends on the pipe. I have a few that came with a bag - carbon fiber sitters, and then the Kenan commission came with a fitted case. To be fair, that was a requirement based on how fragile the design was.
If you look at each pipe’s specs, it should show whether it comes with a case or a pouch. In my experience, however, I’ve found him to be very easy to work with. If someone had their eye on a pipe and it not coming with a case was a deal breaker, I’d be willing to bet that by reaching out to him, a case could be made for a slight charge. I can’t verify this because I haven’t tried, but he’s been great to work with over the last few months, stands by his work, and seems to want the customer to be happy in spite of all else. I also wouldn’t think it would take them too long to get a case made, since my commission was done within about a week and required a custom-fitted case.
