It's not fairly often you see an oil rig or ANY kind of glass, for that matter, that comes with a fused joint housing a damn drain!
The implications of this addition intrigue us quite a bit, we'll admit. We figure it's due to the fact that this rig is just SO tiny that it'd be easier for the user to fill it up from the side rather than be turning and twisting the entire rig every which way. Very innovative!
- Joint Size: 14mm
