FAQs
Please read our FAQs page to find out more.
Is the decal likely to peel or fade over time?
No. The design is heat-bonded directly onto the glass, so it stays vibrant even with frequent use and proper cleaning.
Is it difficult to clean?
Not at all. The classic beaker shape and removable downstem make it straightforward to rinse, soak, and scrub with common cleaners.
Is the 15mm thickness only at the base, or does it apply to the entire bong?
Typically, the 15mm measurement refers to the base thickness. The rest of the bong is still made of thick, sturdy 9mm borosilicate glass.
How do I properly fill it with water?
Fill it enough to submerge the downstem slits by about an inch. Overfilling can lead to splash-back.
Can I add an ash catcher to the Shapes Beaker?
As long as the ash catcher matches the joint size (14mm) and the angle, you can add one to enhance filtration and keep the main chamber cleaner.
