A 20-inch Monark Glass straight-tube bong with an inline jet percolator and color-accent body work — full-size daily driver from a known glass house.
Ships with a free glass bowl. Every bong from Oil Slick Pad includes a free glass bowl slide. Standard joint size, ready to pack.
Twenty inches is the line between "tabletop bong" and "real water pipe." Monark Glass builds in this size for people who want diffusion that actually does something, not a starter bong scaled up. The inline jet perc runs along the body — vapor hits the perc, breaks up, then climbs the 20-inch column for cooling. Color accent work along the body keeps it from looking like generic clear borosilicate.
Daily flower smokers: The 20-inch column gives cooler hits than any 8-12 inch bong.
Group sessions: Big enough to pass around without feeling cramped.
Bong upgraders: Step up from generic 12-inch starters to a Monark with real perc work.
Worth Noting: 20-inch glass needs storage space and careful handling. It's stable when sitting, but it's also tall — keep it where it won't get knocked.

To recap: a 20-inch Monark borosilicate straight-tube bong with an inline jet percolator, color accent body work, 18mm joint with downstem, free glass bowl, and a thick stable base.
For the body: fill about a quarter with 91% iso, add coarse salt, cap the openings, and shake gently in a horizontal position to clean the inline perc slits. Iso/salt the downstem and bowl separately. Rinse all parts with lukewarm water and let them dry standing up. Change the bong water between sessions to keep flavor clean.
A jet perc is a horizontal tube with slits or jets on the underside. Vapor pulls through, breaks against the water, and rises with high diffusion. Less drag than tree percs, more cooling than a basic downstem.
Cover the downstem holes by about half an inch. The perc above the water should stay above the waterline — if water reaches the perc, you'll get splashback.
Not directly — this bong is 18mm. Use the included 18mm bowl or buy an 18mm-to-14mm reducer if you want to use 14mm accessories.
No. Color accents are glass detailing on the exterior — pure aesthetics. The smoke path is clear borosilicate.
