A bong bowl with an integrated screen. The screen fused into the glass holds the material in place, so no separate bowl insert or grate is needed and the downstem does not clog as easily.

The bowl is made from 5 mm thick borosilicate glass and fits all bongs with an 18.8 mm ground joint.

Material: borosilicate glass
