The GRAV Small Deco Beaker is a 6.7-inch borosilicate beaker bong on a 3.9-inch base, running a 10mm bowl and a removable 4.45-inch downstem. It is deliberately a no-frills piece — no percolator stack, no recycler loop, just a properly made small beaker. $79.99.
The 10mm bowl is the unusual spec
Almost every beaker bong on the market runs 14mm or 18mm. This one runs 10mm, and that is a real decision rather than a cost cut: a narrower joint means a narrower airway, which suits a small chamber because it stops the draw from outrunning the water.
It also means your existing bowls probably will not fit. Check what you own before you buy, and be aware that 10mm accessories are stocked less widely than 14mm — a smaller shelf at every shop, though still a standard size.
Removable downstem, and why that matters at this size
The 4.45-inch downstem comes out. On a compact piece that is the difference between a bong you can genuinely clean and one you fight with, because a 6.7-inch body gives a brush almost nowhere to work.
A removable downstem also makes damage survivable. It is the part that breaks most often on any beaker, and replacing one is a few dollars where a fixed downstem cracking is the end of the piece.
Beaker geometry in a small format
The beaker shape earns its place through water volume and stability. A wide base holds more water than a straight tube of the same height, which means more for the smoke to pass through, and a 3.9-inch footprint under a 6.7-inch body is very hard to knock over.
That combination is why the beaker outlasted every shape that tried to replace it. Scaled down like this you keep the stability and trade some chamber volume for a piece that fits a shelf.

Where it sits in the Deco range
GRAV builds the Deco beaker in three sizes and the differences are exactly what you would expect. The Medium Deco Beaker is the middle option and the Large Deco Beaker runs close to twelve inches for a desk.
If you want percolation rather than a plain beaker at similar money, the Oracle puts a mushroom perc into a 7.75-inch body on a standard 14mm joint. The rest of the catalog is on the GRAV Labs brand page.
