This is standard 1.75 mm PCL. It fits low-temperature pens from any brand, including ours. Nobody can strand you.
Why PCL and not PLA
PCL melts at a fraction of the temperature PLA needs, and that is the entire reason a cool-nozzle pen is cool. Feed a low-temperature pen the wrong filament and two things happen: the safety you paid for disappears, and the nozzle clogs. If your pen came with soft, quick-setting filament, this is what it wants.
Not sure which you have? If the pen is sold for children and the tip stays cool, it takes PCL. If it runs hot and takes the same spools as a 3D printer, you want our PLA refills instead.

What it's like to use
- Sets in about ten seconds — fast enough that a child stays interested in what they're making.
- Non-toxic and biodegradable. PCL is plant-derived and odourless. No fumes, no smell in the room.
- Won't scorch the nozzle, which is how most low-temperature pens die.
- Bright, opaque colours that hold their shape once cool.
