A 255ml bone china flat-bottom dripper for 1 to 2 servings, made to sit on a transit base for switch-controlled brewing or a bamboo holder for a standard pour over
The Tri-Spin CT Flat Dripper from DragonFly Design Center is a new bone china flat-bottom pour over dripper built to close that gap. It starts from the CT62 conical dripper and rebuilds it around a flat bottom, with a grooved inner wall and DragonFly's Tri-Spin base.
How the Tri-Spin CT Manages Flow
The inner wall is a flat surface cut with 12 long grooves and 12 short grooves. The filter paper adheres to a larger area of the wall, so there is less room for water to bypass the bed and more of each pour passes through the grounds.
The grooves act as flow guides and pressure relief channels, which keeps the drawdown smooth and the extraction even across the bed. The result is a even extracted cup with clear layers of sensory expression.
At the base, the Tri-Spin hollowed design with multiple grooves spreads the water's exit points to avoid concentration in the center. This reduces the risk of the clogging and helps water move through the whole bed. This matters even more with larger doses, where localized over-extraction is more likely.
DragonFly developed the CT Flat with competition brewing in mind, where a stable, repeatable extraction counts for more than speed.

The Shanwen Jia Exterior
The outer wall carries the Shanwen Jia (山文甲) pattern first used on the CT62. Shanwen Jia, also known as Shanwen Armor, is a Tang Dynasty armor recognized by its repeating mountain pattern. On the dripper, that pattern wraps the outer wall as a continuous geometric repeat.
The exterior is the link between the two brewers. The CT62 pairs it with a conical interior, and the Tri-Spin CT pairs it with a flat bed and a grooved wall.

Product Details
Brewing with the Transit Base or Bamboo Flat Dripper Holder (Purchase separately)
Paired with the DragonFly Flat-Bottom Transit Base, the dripper brews two ways. With the transit knob open, it runs as a flat-bottom pour over and gives a clean, filter-style cup. With the switch closed gives a fuller, immersion-style cup.
You can also choose to brew with a Bamboo Flat Dripper Holder – using it as a traditional pourover dripper.
It holds 255ml, brews 1 to 2 servings, and takes foldable flat-bottom filter paper or 185 flat-bottom paper filters.
The Groove Structure and Tri-Spin Base
• Groove structure: Twelve long and twelve short grooves on a flat inner wall let the filter sit closer to the wall while still guiding flow and relieving pressure.
• Tri-Spin hollowed base: Disperses the outflow instead of concentrating it in the center, which reduces clogging at larger doses.
• New bone china body: Heat resistant to 120°C (248°F). Safe for dishwashers, microwave ovens, and dish dryers.
