i LOVE phunnels. they are very ingenious and a great investment in the long run. they dont necessairly need to be used with just the tangiers brand, but it can be used with any, its better with juicer brands like starbuzz however. They make cleaning a stem incredibly easy (most there will be is a little ash) and a bowl is easy to deal with.
if you can get them very soon. you wont regret the ease of them, and on top of that the long sessions you will get from even a small one
