BLAZE GLASS Diffusorchillum ‘Big Bob’ 14 cm | 29,2>18,8mm

Blaze Glass bongs are made of stress-free 3.1 borosilicate glass (comparable to Duran glass) of the highest quality. At least 5 mm wall thickness makes a water pipe robust.
We use extremely accurate standard ground joints in 14.5 or 18.8 mm. Depending on the bong geometry, normal ground joints, reinforced ground joints and bi-stable ground joints (double wall) are used in our products.
