Precision Panel Line Pen
LayersCrafts LinePro™ Precision Panel Line Pen
Flat model in. Sharp detail out. Ultra-fine stainless steel nib with natural capillary action — crisp panel lines on 3D prints, mecha kits, minis and scale models. No oversized brushes, no mess.
Flat Model In. Sharp Detail Out.
Steel Nib · Capillary Action · 3 Spare Nibs Included
Engraved details deserve better than an oversized brush. The ultra-fine stainless steel nib pulls ink straight into recessed grooves by natural capillary action — less overflow, less smudging, less cleanup. Crisp panel lines on 3D prints, mecha kits, minis and scale models, every single pass.
Built Like A Tool. Not A Toy.
Every part of LinePro™ is engineered for one job — pulling perfect lines into engraved detail, session after session.
The Capillary Nib
Touch the tip to an engraved groove and the ink flows through it by itself — natural capillary action pulls panel line fluid exactly where it belongs, and nowhere else. Fine lines, armor panels, weapon engravings, vehicle details: one touch, clean coverage.
The Aluminum Body
A 133mm premium aluminum alloy barrel, lightweight and perfectly balanced for the steady hand detailing demands. Comfortable through long sessions — no cramping, no wobble, just control from the first line to the last.
Built For Years, Not Projects
Every LinePro™ ships with 3 stainless steel replacement nibs — swap in seconds and keep the same precision for years. Compatible with most enamel-based panel line accent fluids and hobby detailing inks. Panel line ink sold separately.
The Old Way Vs. LinePro™
The oversized brush that came with your panel line bottle was never made for precision. Here's what changes when the tool matches the job.
The Bottle Brush
- ✕Floods the groove — ink spills over the panel edges
- ✕Smudges and fingerprints during cleanup
- ✕Wastes ink on every single application
- ✕Endless thinner and cotton swab cleanup
The Precision Nib
- ✓Ink flows only in the groove — capillary action does the work
- ✓Crisp, clean edges with barely any excess to remove
- ✓Uses only the ink you need — bottles last far longer
- ✓Faster detailing — more painting, less cleanup
Same ink. Same model. The only difference is the tool.
From Flat Toy To Detailed Machine
Without panel lines, every engraved detail disappears into flat plastic. One pass of LinePro™ later — depth, shadow, and mechanical realism in every groove.
