This 'Blaze Glass' pre-cooler has a shower head diffuser with 10 slits and an additional recycler. In the first stage, harmful substances are well washed out and the smoke is gently cooled. The second stage (recycle) refines the smoke - a special treat! The characteristic feature of 'Blaze Glass' quality is its robustness due to a glass thickness of about 4mm.
Please take note of the angle!
