FAQ

Q: Why choose a Circ Perc over a Tree Perc or Honeycomb Perc?

A: Circ percs offer the best of both worlds! They are sturdier and less fragile than tree percs while being far easier to rinse clean than tight honeycomb discs.

Q: Is this 38cm straight tube bong easy to clean?

A: Very easy! Because resin doesn't get trapped in tiny holes, a basic rinse with isopropyl alcohol and coarse salt clears out buildup right away.

Q: Does it come ready to use?

A: Yes, it includes a matching 14mm bowl and downstem so you can enjoy smooth sessions right out of the box.
