The high standards from the North American manufacturers The Mill rarely disappoint and this exotic wood example is no exception. The Z-5 has a smoke thru cap which further heightens the vibration level. Z pipes are retro, going back to the seventies and are some of the oldest designs from the Mill. This smoke-thru capper is made of Honduras rosewood with a bloodwood cap. Shaped to resemble a guitar, it makes a great concert wood pipe.
