Do the caps for Savinelli Tortugas work well at staying in place and containing partially smoked bowls to be finished later, or fresh bowls to be smoked later? Are the caps durable? Do they use too much of the chamber volume? Thanks.
The Savinelli Tortugas are great on all counts, though you can make any pipe into a Tortuga with one of these silicone Save-A-Bowl dealies. I get the impression they were not originally designed for tobacco pipes, though I've been using them every day for about a year now and they certainly work great on all my pipes for taking a fresh bowl with me or stowing away a partially smoked pipe in my pocket to finish later.
