Roor Zumo Bong 4.2mm



This is by far the largest roor bong ever produced with a massive internal diameter which is brought in at the mouthpiece. The downstem ships as a 18.8 and a 29.2 ground joint size. The 29.2 joint size is genuinely HUGE allowing for a full "chug" through with minimal drag. For those wanting to use their 18.8 bowls with this larger joint size you can purchase a 29.2 to 18.8 convertor. A bright vivid orange label sets this beast apart and it is made from 4.2mm glass. Complete with a bistabil joint and huge base for stabillity.

The roor bongs premium range comes in the following thicknesses 3.2mm, 5mm, 7mm and a one off 4.2mm. Each glass pipe in the premium range reflect the passion the artists at roor have for manufacturing only the finest glass smoking pipes money can buy. Their expense is reassurance to you, the user, that what you are buying is a hand made product of the highest calibre, lovingly made to ensure that each piece is the perfect smoking implement.

Roor Bongs creator and owner Martin Birzle personally oversees his artists at the studio in Frankenthal ensuring that each piece is lovingly made, and then signed by the artist involved. You can tell the different thicknesses by their standard colours, red is 3.2mm, white or black is 5mm, green is 7mm and yellow is a fairmaster bong which is 5mm
