A brush marker gives the line of a paintbrush inside a pen. The tip is a flexible bundle of nylon fibers, not a rigid point. It flexes under the pressure and springs back when the pressure lifts, so the stroke goes thick on the downstroke and thin on the hairline. A thick refill brush marker adds one thing to that tool: when the ink runs out, the pen does not. The barrel refills and the tip stays.

The tip is the reason the pen is worth refilling. A cheap tip frays after the first refill and the point goes soft. A durable tip holds its shape through the multiple refills and still comes to the fine point at the end of the stroke.
The thick tip covers the broad areas and the fine lines from the one tool. The letterer does not switch between the wide brush and the fine liner. The tip does both.
The refill is why the pen stays in the kit instead of going in the bin. The barrel accepts the cartridge or the bottle of ink. The user replaces the cartridge or drips the ink into the reservoir.
The pen that refills easily gets refilled. The pen with the complicated system gets thrown away with the half the ink still inside. The thick refill brush marker with the simple refill keeps the tool in service.
The larger reservoir goes longer between the refills. The long lettering session does not stop in the middle for the refill. The ink capacity and the tip life move together, and the pen that runs dry before the tip wears out wastes the tip life.
The barrel is the grip. The letterer holds the pen for the hours, and the barrel has to feel balanced in the hand. The cap seals the tip so the ink does not dry between the sessions. The cap that does not seal turns the refillable pen into the disposable one.
Here is what a thick refill brush marker has to deliver:
The letterer uses it for the calligraphy practice, the downstrokes thick and the upstrokes thin. The illustrator uses it for the inking and the variable line weight. The student uses it for the daily practice, and the refillable design keeps the cost per session low.
The tip goes soft because the fibers were cheap. The durable tip holds. The ink stops because the reservoir was empty and the refill was not done. The refillable design is the answer. The cap does not seal and the tip dries between the sessions.
A thick refill brush marker is the brush pen that refills instead of retiring. The tip bends and returns. The barrel refills. Choose a marker with the durable tip and the simple refill.
